Matrix has screensharing but no audio for the share, at least from when I’ve tried it

No they don’t. Check out my other reply.

TLDR, they plan to but haven’t yet. But currently they (the owners of the centralized instance) have the ability to read other people’s chats due to the lack of E2E encryption

Reposting my reply from another thread, just to keep people informed:

Keep in mind everyone that Stoat still doesn’t currently protect it’s users information and is centralized. It doesn’t use encryption but it is very seamless. You can host your own Stoat instance but it doesn’t communicate with the main one. The devs have said they plan to add more security features in the future yet still don’t make it a priority. The host of Stoat should be able to see everyone’s messages, including in DM’s, due to the lack of E2E encryption. Once they add more security features I imagine they will be much more popular in general.

Or use a virtual camera with a preset video

This doesn’t work for age verification and is a relatively small pool of photos
