10 common misunderstandings about the GPL

The GNU General Public License (GPL) is one of the most widely used software licenses -- and, undoubtedly, the most misunderstood. Some of this misunderstanding comes from hostile propaganda, but some also comes from a lack of experience in licensing issues on the part of both lawyers and lay users, and the use of standard language in conventional end-user license agreements that are unthinkingly coupled with the GPL. In all cases, the confusion is frequently based on misreadings, rumors, secondhand accounts, and what is convenient to believe.
