In my case, I don't care about the "privacy protection" of a given social network: I assume that everything I post is public (except private messages), so I filter what I upload based on that assumption.

Things I do care about:

-No censorship

-Chronological feed

-Open source & non-abusive client. (i.e. no tracking what users see or read)

-Good usability

I don't care about abusive content or fake news. If I see fake news, I just stop following whoever posted it.

So, under my criteria: decentralized > facebook
