I could see the login part being nice, but I still don’t really see the value in federating chat text. Honestly that would be a negative to me, I don’t really want my chat messages copied and federated out to other servers forever. Similarly, why would I want to view a chatroom through Lemmy? Why wouldn’t I just want to go to that community through it’s app or site or whatever?
It just feels a bit like blockchain all over again. Federation and activitypub are great tools for some purposes but people seem to want to use them for everything.
Calls and easily sharing my screen are 90% of my use cases for Discord. The entire appeal of it initially was that it was a more functional Ventrilo with both text and voice channels. Hopefully something FOSS gets further developed by the time Discord completely shits the bed.
