Apple actually offered the LLVM work to be contributed and integrated into the gcc
The offer was refused
Later, the gcc adopted, late and haslty, many of the features LLVM had
I guess that accounts or another successful non GNU project
with the added bonus of offering an example for the manuals of the pettyness that is a landmark of Richard Stallman's personality and hence of the GNU project as a whole, let alone many of its minions
@abbienormal The offer wasn't refused. This is FUD.
@abbienormal According to the comments to the article (which cite the actual GCC mailing list), the problem was that Apple refused to give the FSF copyright over the changes, which is customary for every contribution, at least in GCC and Emacs that I know of.
Also, they could have licensed LLVM as GPL whenever they wanted, but they never did.
