Yeah I think I agree.
The big difference I see is in the chip. The PowerPC arguably had its benefits (vectorization) which made it super attractive for bioinformatics, etc., and a lot of that software was Linux-based. People could either buy a super-computer or a G4 (or a cluster of G4s) and get the work they needed done for a fraction of the cost. MacOS (and OSX) were behind on a lot of this stuff compared to Linux then.
Today from what I see the M3-M5 chips are a big leap forward compared to their competitors, and it just happened to hit at the same time LLMs became popular. I imagine there are some similar, specialized needs with the M[1-5] chips that might benefit from Linux but with OSX's stronger BSD underpinnings it's a different world.
