I am really confused how it's supposed to be "decentralized" if you have to have a sign-in with a specific provider to use it.

Can you log in if Blockstack-the-company goes down or has a technical issue?

Your identity is on the blockchain and that is decentralized so even in that case you or anyone can run a separate node to handle them. Also all the auth library is open source so anyone can work on that.

Its a distributed database, it doesn't matter if the blockstack company takes a long walk off of a short pier.
