> A centralized service runs on computers wholly under control of a single entity. They can change, monitor, amplify and bury all information. They can read your private messages. They can delete content, promote other content, and even impersonate you.

Apart from reading your private messages, does that mean you still need to trust that the server you’re connected to isn’t doing all those other things?

Nope. You own your keys, and you can switch to a different server instantly while retaining both your username and your followers. They can't impersonate you because they don't have your keys. They can't ready your messages because they don't have your keys.

It's a bit more complex underneath (e.g. the are light-clients that you can entrust with part of your key), but that's the gist.
