GCC mailing list's reaction to NASA/Nvidia's LLVM Fortran announcement

I saw this bit "Basically NVIDIA bought PGI and now is open source their fortran front-end. Nothing magical really. Basically NVIDIA is trying to have the "community" do more of their development for them. This is an anti-open/free source way of doing things" and I'm not totally sure I understand the author's point.

The entire thread basically focuses on "whatever, they're not really shipping in 2016" instead of a more positive: "Cool! Another bit of compiler infrastructure being turned open-source!".

I understand that many people find the GPL to be the only truly "free" license, but it seems uncouth to be so hostile to what is ultimately a positive outcome.
