Indeed, and to add on to this, I suspect that they had their own plans about where to take the client space in general, which involved more avx512 (which a couple of generations prior to alderlake supported!), but depended on their having a near-monopoly. The competitiveness of zen forced them to pivot, and avx512 fell to the wayside, largely because of its lack of users (which in turn is in large part because no one really cares about performance on clients).
