Apart from "trying to implement this will cost us more in CUDA API copying lawsuits then it could earn", I don't know.

But it's not just that they can't make competent software. It's that everyone tells them they should try, that it looks like a pile of money ready to pick up, that people try doing it on their own... and AMD does nothing. They're not even taking the chance to fail/succeed. Can you imagine that Lisa Su doesn't get asked about this at least once a week?

They are already trying to copy CUDA API with rocm and HIP. If this is lawsuit worthy, they may already be hit with a lawsuit at any moment.
