Right, but my point is that this isn’t some famous malicious intentional lock-in by “evil Microsoft” — it’s how every console is designed. (And arguably Xbox has an advantage here because it shares DirectX with Windows)
Not really. It has nothing to do with console idea or form factor, it's just how these messed up companies are "designed" in using anti-competitive methods. See Steam Deck which uses Vulkan just fine.
There is absolutely lock-in in MS and Sony's approaches. There is no inherent need in it just becasue it's a console.
There’s no evil MS lock-in here.
