Just remember that MetaMask is nothing more than a front-end you have the choice of using to access your Ethereum (or whichever) wallet and then interact with the network itself.
They can collect data about you, but MetaMask can't block users from their actual wallets.
As long as the underlying network remains decentralised, then it doesn't matter what MetaMask do or say.
If you don't like the way they operate, then just use another front-end to access the underlying decentralised network.
