GPL is cancer, its never solved a thing. Denying that is like calling the earth flat. It has some use, but closed source sw has always been just as good.
Worth noting that Intel has dropped their "old" compiler and the newer "Intel" compilers are LLVM based.
IMHO they will likely be pulling similar anti-AMD tricks with it and they are keeping their paid version closed source - which is allowed by LLVMs license.
RMS was right that compilers should be GPL licensed to prevent exactly this kind of thing (and worse things which are haven't happened yet).
On another compiler related note, I find it insane that GCC had not turned on vectorization at optimization -O2 for the x68-64 targets.
The baseline for that arch has SSE2, so vectorization has always made sense there. The upcoming GCC 12 will have it enabled at -O2. I'd bet the Intel compiler always did vectorization at -O2 for their 64bit builds.
