TBH, Nvidia kinda deserves this. Between the incredibly buggy forcedeth ethernet chipset, the 2010 era laptop GPUs with insane failure rates that caused a recall across the entire industry, and various other issues, Apple (and others) have legitimate reasons to avoid working with them.
Both of those issues are over 2 decades old. It's the equivalent of boycotting Apple for supporting IBM, you will not achieve anything since the "problem" is already fixed. I don't know how you can call that legitimate in good faith.
Apple had the opportunity to take Apple Silicon to the datacenter and become the #1 professional ARM microarchitecture in the world. It was Apple's stupid grudge that gave Nvidia everything they needed to sell thousands of their lazily-made Grace CPU.
