As for AMD v Nvidia, imho it's more often a matter of AMD drivers being buggy even if their hardware seems to be almost on par in terms of performance, also right now NVidia has ridden high on both blockchain and now AI trends thanks to CUDA being propietary.

And the third paragraph is my point, porting would've been trivial instead of requiring another engineer if they had supported more standard API's, but they refused and now they're hedging their bets on another manufacturers API. It's just such a roundabout way of saying that they feel the pain without going back and fixing the basics.
