I’m not sure why Web Push is often singled out for this criticism, the same goes for app notifications. I’ve never actually gone down the road of creating one but in theory you could make an almost entirely decentralized peer to peer messaging service with a PWA implementing the Web Push API to exchange messages. I agree that sadly most of the use cases are spammy nonsense but it remains an interesting API to me.
