I she to read your comment again as it just doesn't make much sense to me. How can notes be centralized through relays? How? How? If I am posting my notes to 100+ relays and they all store my data, that is the absolute definition of decentralization. With ActivityPub, I store my posts on ONE server. Sure, dozens and dozens maybe even hundreds of severs exist, but using your words, they're centralized through each serverz because of the mast.to server goes away in an instant, all users that use it also lose their data and entire social graph. ActivityPub is more distributed computing and not decentralized computing.
