I dont think there are any federated chat systems with support for group calls and screensharing besides matrix. Maybe xmpp but i think its not natively implemented and more of a client add on. Matrix still misses some things (like sharing application audio) but its the best we got if you dont want to get caught in another unfederated enshittification spiral.
Are stoat and fluxer federated? Don’t have time to watch the video right now.
Last I heard, Stoat isn’t planning federation.
Fluxer IS planning federation. https://blog.fluxer.app/roadmap-2026/
