You can't simply go around and change licenses, unless you are the
copyright
holder!
But you are the copyright owner of the LilyPond code.
Copyright belongs to the person who wrote the code (sometimes). There is
no ONE owner of lilypond - it is spread amongst many.
Indeed I personally MIGHT own some copyright in lilypond! There's a good
argument I do, it's a grey area!
That's the paperwork that is needed: Every contributor, who has until
now contributes as GPL v2only, needs to agree to change his/her
contributions
to GPL v2+. Unless you track down every substantial contributor (git
helps in
that regard), LilyPond can't switch to GPL v2+.
Why? Is there a GNU requirement? - My cursory reading of v3 did not
find anything like that. Where does this idea come from?
It's nothing to do with GNU. It's the law.
Cheers,
Wol
