What I meant by “walled garden” is about federation and not commits, like look at the Signal app federation situation, they rejeted it because it might be confused with cyptocurrency, which I did hate because of its volatility

ActivityPub does support extensions (looking at you, ForgeFed, as an example), but you can be right depending on which protocol they could choose

Actually not, it allows you to interact from different servers from a single account in one instance

Didn’t inted to say that anyway but my changes to thread body couldn’t be send to this community’s instance

I edited that out

Edit: I was typing that out because someone thought they would develop their games there
