A slight exaggeration, but yes, that's quite close to the OP's argument (Git is GPLv2 and will not change; Hg is GPLv2+ and therefore closer in spirit to GNU's goals and a GNU project like Emacs should favor GPLv3 and AGPL tools). Luckily, that particular argument is thoroughly rebutted downthread. Choice quote: "Emacs shot itself in this foot already" by choosing Bzr, GNU's blessed VCS, for such political reasons. (Worth noting: RMS raised no strong objections to Git.) Also, the OP is called out for not understanding the driving reasons for moving Emacs to Git. Edit: Corrected reference to Hg's license; it's GPLv2+, not GPLv3.
