Apple does and other big tech are just an acquisition away from being able to do it as well. In fact if memory serves me right Apple in-house chips were originally derived from an acquisition.

I wouldn't be surprised if Microsoft or Google would buy AMD or Intel (or subdivisions of them) at some point in the future.

This is all speculation of course, and you are not wrong about Nvidia being harder to replace. I mentioned this myself in my previous post, but I don't discard the possibility of it happening.
