The rumor started from a OSNews story  that reported, "it started with complaints received about the content on Planet GNOME, and ended with people proposing and organising a vote to split GNOME from the GNU Project." The real origin point of this is a thread  in the GNOME mailing list titled "Code of Conduct and Foundation membership." This long discussion was participated by Richard Stallman. He wrote , ".. they (developers of non-free software certainly shouldn't promote them (non-free softwares) on Planet GNOME." In another thread, he wrote , "GNOME should not provide proprietary software developers with a platform to
present non-free software as a good or legitimate thing.... It should not invite people to talk about their proprietary software projects just because they are also GNOME contributors" and  "GNOME is part of the GNU Project, and it ought to support the free software movement. The most minimal support for the free software movement is to refrain from going directly against it; that is, to avoid presenting proprietary software as legitimate." In reply to RMS, Philip Van Hoof wrote , "I propose to have a vote on GNOME's membership to the GNU project." Things were getting more complex, as is evident from this post  by Lefty "If muzzling people is a condition of being "part of the GNU project", then maybe we should rethink _that_ aspect of things. Maybe the FSF should start its own planet and set its own rules there rather than attempting to impose its various litmus tests on the contributors to Planet GNOME."
