While the consumer is forced to purchase their consumables from a single source, this is often not considered lock-in because the cost to change, especially in the razor and consumer printer examples, is limited to the inexpensive non-consumable plus any unused, proprietary consumables remaining at the time of change.
Additionally, since 1989, interchangeable lenses have often had electronics in them to communicate with the camera body. Manufacturers attempt to create lock-in by not disclosing how the lens communicates, requiring competitors to either pay licensing fees for the information or else reverse engineer the system. Further, many parts of camera systems besides lenses are subject to vendor lock-in; there have been unique designs for film canisters, flashgun connectors, electronic cable releases, and many other items. Consumers wishing to switch brands are thus required to replace not just the camera, but also the lenses and many accessories, often a complex and expensive proposition.
SIM locking may be considered a vendor lock-in tactic as phones purchased from the vendor will only work with SIM cards from the same network. This creates additional hassle to the buyer as the phone cannot use a prepaid SIM from a different vendor while on vacation(a common tactic used by Asian tourists visiting another Asian country) and as a result the subscriber must also sign up the often pricey roaming service offered by the vendor . Additionally, should the subscriber wish to take out a second line for any reason, he/she must also get the line from the same vendor as the sim card of a competing vendor will not work. Sometimes, even the SIM card from the same vendor will not work and the buyer will be forced into buying another phone.
Various standards organizations, such as the US Department of Transportation regulate the design of certain automobile components to prevent vendor lock-in.
The Filofax brand of personal filing and diary products, for example, is not compatible with standard paper and ring-binder sizes, so users can buy additional filing supplies only from Filofax or a limited number of other suppliers. Costs are several times those of comparable stationery supplies in standard sizes and formats.
This can make it difficult to switch systems at many levels; the application program, the file format, the operating system, or various pieces of computer hardware ranging from a video card to a whole computer or even an entire network of computers. Note that in many cases, there are no technical standards that would allow creation of interoperable systems. At nearly any level of systems architecture, lock-in may occur. This creates a situation where lock-in is often used as leverage to get market share, often leading to monopolies and antitrust actions.
The European Commission, in its March 24, 2004 decision on Microsoft's business practices, quotes, in paragraph 463, Microsoft general manager for C++ development Aaron Contorer as stating in a 1997-02-21 internal Microsoft memo drafted for Bill Gates:
Microsoft's application software also exhibits lock-in through the use of proprietary file formats. Microsoft Word and Microsoft Outlook both, for example, use proprietary datastore files and interfaces which are impossible to read without being parsed, and such parsers may in turn not be able to exist legally without performing reverse engineering. For example, to access data contained in Outlook's '.PST' files, the application must process the request through Outlook instead of directly handling the file. Present versions of Microsoft Word have introduced a new more open format MS-OOXML. This may make it easier for competitors to write documents compatible with Microsoft Office in the future by reducing lock-in, but as a competitor to the OpenDocument format, it is feared by many such as the FSF that future versions will have features that cause vendor lockin.
Apple often makes use of new or unusual hardware systems; they were the first vendor to make widespread use of Sony's 3.5" floppy drive, devised their own ADB system for keyboards and mice and their own networking system (LocalTalk). In all of these cases, 3rd party peripherals were available and in all of these cases, an argument could certainly be made that the solution Apple chose was superior in many ways. Still, the number of 3rd party providers was more limited than for the competing IBM PC platform (though larger than for the Amiga, which had similarly unusual components) and 3rd party providers sometimes had to license elements of the interface technology, meaning that Apple made money on every peripheral sold, even if they did not manufacture it.
More recently, the iPod, iPhone and iTunes products have been subject to significant vendor lock-in. For example, when you buy an iPod, your only music organization software choice is iTunes, which only operates if you also install QuickTime, which only installs in a mode that changes functionality in Firefox so that when you click on any mp3 file from any website, Apple's QuickTime will open instead of your web mp3 player technology of choice. Therefore, buying an iPod means that your Firefox choices are taken away, even though the use case of Firefox is completely unrelated to the use case of an iPod.
When digital music files with digital rights management are purchased from the iTunes music store, they are encoded in a proprietary derivative of the .AAC format that is only compatible with Apple's own iPod and iPhone portable digital music players, as well as the Motorola ROKR E1 and Motorola SLVR. As a result, that music is locked into the iPod, and if an iPod fails, the library of music is only available for portable use through the purchase of one of the above players. (Even though the DRM and AAC songs purchased through the Apple iTunes are technically locked to the iPod, this can be circumvented by burning the purchased tracks to a cd in audio format, then reintroduced to the iTunes software. The change in burning and importing preferences are made and iTunes will import the songs in mp3 format without the DRM restrictions. This is all accomplished at the waste of a CD-R. However there will be a slight loss in audio quality due to the conversion to CD-Audio format and back again)
In January 2005, an iPod purchaser named Thomas Slattery filed a suit against Apple for the "unlawful bundling" of their iTunes Music Store and iPod device. He stated in his brief: "Apple has turned an open and interactive standard into an artifice that prevents consumers from using the portable hard drive digital music player of their choice." At the time Apple was stated to have an 80% market share of digital music sales and a 90% share of sales of new music players, which he claimed allowed Apple to horizontally leverage its dominant positions in both markets to lock consumers into its complementary offerings. In September 2005, U.S. District Judge James Ware approved Slattery v. Apple Computer Inc. to proceed with monopoly charges against Apple in violation of the Sherman Antitrust Act.
As of 29 May 2007 tracks on the EMI label have been made available in a DRM-less format called iTunes Plus. These files are unprotected and are encoded in the AAC format at 256 kilobits per second, twice the bitrate of standard tracks bought through the service. iTunes accounts can be set to display either standard or iTunes Plus formats for tracks where both formats exist. These files can be used with any player that supports the AAC file format and are not locked to Apple hardware.
On June 7 2006 the Norwegian Consumer Ombudsman Bjørn Erik Thon stated that Apple's iTunes Music Store violates Norwegian law. The contract conditions were vague and "clearly unbalanced to disfavor the customer". The retroactive changes to the Digital Rights Management conditions and the incompatibility with other music players are the major points of concern.
Examples of Sony's formats include
As of 2006, Sony digital cameras typically use Memory Stick cards that can be acquired only from Sony and a few select licensees, and this memory is typically much more expensive than alternative memory types available from multiple sources. This is a clear example of lock-in because other camera makers do not use memory types that they have invented and which are unique to their brand of camera.
In contrast, Blu-ray Disc was developed by a large group of manufacturers which includes Sony but in which they do not have a controlling position.
The term Connector Conspiracy was coined to describe this situation, and implies the worst case scenario of a cabal of manufacturers colluding in secret to sell incompatible connectors. Yet actual lock-in attempts can fail, if adapters can be purchased or manufactured to make the components compatible. SCSI and RS-232 have been rumored to be instances of Connector Conspiracy.
Since the late 1990s, the use of free and open source software (FOSS) has been pushed as a stronger solution. Because FOSS can be modified and distributed by anyone, the availability of functionality cannot tie a user to one distributor. Also, FOSS tends to adhere faithfully to standards. The ineffectiveness of distributor lock-in means there's no incentive for FOSS developers to invent new data formats if usable (royalty-free) standards exist.
In particular, copylefted FOSS is particularly resistant to the above mentioned "EEE" tactics since anyone distributing modified versions cannot legally prevent free or competing redistribution of the modifications and their source code.
