It was a great start, but you need to adapt or you perish.
Specially when propietary dependencies kill thousands of projects at once.
I, for one, am happy that there are still a couple of people here and there that you can really trust on this stuff.
That gave vendors more freedom and flexibility (to lock their software away from their customers.)
As usual, customers got less freedom and flexibility.

This is not a given, even outside of compilers. It's a heck of a cope there.
I was responding to this, which is more widespread than GCC (although it was one of the first wins of the GNU).
There were various companies who wanted to add on backends and other bits to GCC, but wouldn’t due to the license. That’s one of the reasons LLVM is so popular.
But when this realization comes, it will be too late.
I think without GNU/Linux, most likely all UNIX vendors would have a better market share today.
