My main worry is when they start entrenching network effects that become hard to undo. For example, if we start normalizing "sign in to this crypto social thing with Google", I think that's really bad, UNLESS it's done in an account-abstraction way where under the hood it's using zk-email and individual users can sign in with their ethereum account instead (and convert their account from one to the other). This way, it's not entrenching network effects of centralized web2 platforms, it's actually creating a bridge that lets users join the ecosystem with them, but then more easily migrate away from them.
