I think GPL and copyleft in general is getting less and less relevant as time goes on. Looking at GPL specifically it relies on scarcity. The reason companies would agree to the terms of the GPL in the 1980s, 90s, and even 00s was if you wanted a good compiler, parser, kernel, or library you had only so many choices. There might have been only a few thousand people in the world capable of writing a mature compiler suite at some points. So if you're $MEGACORP you could either a) buy a proprietary compiler, b) pay for rarified (so expensive) talent to write your own, c) tolerate the terms imposed by the GPL. Most companies saw option "C" as the more cost effective one. Now there is a lot of computer science talent out there, so the price of option "B" goes way down. Why tolerate the GPL when I can hire any of the people laid off from Microsoft, Meta, Oracle, Amazon, come work for me, and all of them probably wrote a compiler in college and I get to own the code outright. Or, I can use FreeBSD, LLVM, whatever, and maybe there is a chance for $MEGACORP to contribute back, where in option "B" there is almost no chance. And this doesn't even take LLMs into consideration.
