I lean the same way. I signed up with an alias and got instantly banned.

Their support also drops certain alias emails, so there's no way to appeal.

A "decentralized" network that locks you out for using basic email privacy tooling, with zero recourse, is centralized where it counts.

If you wish to avoid downvotes you might benefit from stating why you think ActivityPub’s decentralization is superior. We’re in a thread discussing an example of Bluesky decentralization so it’s clearly possible.

ActivityPub is a terrible protocol. The protocol isn't what the specs are, and there's not even a consensus de-facto spec beyond "what Mastodon does". Atproto is a bit better.

Atproto is terrible at decentralization however, because of the model where data is stored decentrally, but accessed centrally, in big servers that need to be aware of all the data. In the ActivityPub model there isn't such a thing as "all the data" - you see what you see.
