Critics say that frequent users of the phrase (or similar variants) are simply expressing elitism, and that their attitude drives away newcomers without helping them. Their time could better be spent adding the question and answer to a FAQ, pointing the user to a helpful website, or simply not responding. They point out that RTFM is often used when it is not even clear which manual their correspondent should be reading. One of the most frequent criticisms of the open source community is lack of friendly support for newcomers. The Ubuntu Forums and LinuxQuestions.org, for instance, have instituted "no RTFM" policies to promote a welcoming atmosphere..
This phrase is also commonly used in Massive Multiplayer Online games, from people frustrated by newbies asking how to do something that is explained in the manual.
Some hackers have suggested that in some situations "RTFM" is actually the best advice that an aspiring hacker can receive. They posit that hacking is a dynamic art which requires independence and drive on the part of the hacker, and see "RTFM" as more of a long-term advisement than it is a response to any single query. This argument is only applicable when used with other hackers, however, given that the concepts surrounding open source software are designed to be suitable for use by non-hackers. In fact, usability experts recommend designing some kind of software to be usable without a manual at all, since users don't ever actually read them. Although, of course, there is the argument that users don't read manuals because designers, knowing that users don't read them, don't bother to make them very useful. Regardless of original cause, this problem could be mitigated as the 'contextual help' paradigm comes into play.
