And?  For your argument to work, we'd need to have the kernel somehow
locked into the use of tools that would have no non-GPL equivalents
*and* would be (somehow) protected from getting such equivalents.
How could that be done, anyway?  Undocumented and rapidly changing
features of the tools?  We would get screwed by those changes ourselves.
Copyrights on interfaces?  Software patents?  Some other foulness?

I honestly wonder about the mental contortions needed to describe
something of that sort as "free", but fortunately we are nowhere
near such situation anyway.

I don't like Rust as a language and I'm sceptical about its usefulness
in the kernel, but let's not bring "gcc is better 'cuz GPL" crusades
into that - they are irrelevant anyway, since we demonstrably *not*
locked into gcc on all architectures your hypothetical company would
care about, Rust or no Rust.
