Well, as I remember, the thing about solid is it’s a protocol. So, if you don’t trust one vendor, you can trust another vendor or implementation without losing interoperability. So it goes the opposite direction of consolidation because it allows arbitrary storage services to be used transparently by arbitrary services in a secure fashion.

They said that about OpenID and now you have the choice of ~three bigtech ID providers.

…Google, …and? Who are the other two?

Maybe you're thinking like Facebook, but AIUI, login with Facebook is proprietary. The problem there isn't the protocol, it's that companies are massive. If anything OIDC lowers the barrier to entry, assuming RPs properly support it (which is a huge if, but if these were 3 proprietary protocols instead of 1 standard one, there would have never been a chance…)
