The value is the network and it's hard to get a person's entire network to move over at once. You're right that most people don't care about "decentralization", but they really care about not losing access to their account, avoiding hate/bullying, and many other things. A Mastodon type decentralized platform where you join the server that best aligns best with your interests/needs is one way to solve this. More friction though, so not sure on what will win out.
