I thought GPLv3 adoption by GCC was what really lit the flames on moving to llvm by commercial entities?

you only need to worry about GPLv3 if you are modifying gcc in source and building it and distributing that. Just running gcc does not create a GPLv3 infection. And glibc et al are library licensed so they don't infect what you build either, most especially if you are not modifying its source and rebuilding it.

And what we've seen from e.g. Apple is that "make a private fork and only distribute binaries" is exactly what they wanted the whole time.

That's the context here. If you build a new compiler based on GCC, GPL applies to you. If you build a new compiler based on LLVM it doesn't.

Still some companies try hard to avoid GPLv3, see Apple, who either provide old GPLv2 licensed software or invest in BSD/MIT replacements.

You might know this history better than me.
