> AMD is a fabless chip designer (like nearly everyone except Intel and Samsung)
Okay, but they didn't used to be. They sold all their fabs. And when their reliance on third-party fabs meant they couldn't keep up with Intel, they did... nothing. Now, you could argue that they don't have the resources to do anything. But that doesn't mean it's not their fault that they didn't do something, it just means they couldn't.
Let's not forget to that they had to sell the fabs due to Intel anti-competitive market squeezing. They would offer the chips for free, but vendors would still be better off with the Intel kickbacks.
They were later compensated, but the damage done was incredibly destructive.
