BigBlueButton
I love being able to offer an alternative to zoom - here is my blog on that: https://agaric.coop/blog/why-we-resist-zoom-and-choose-bigbluebutton-video-chat
I am a member of http://meet.coop and we are building a cooperative of BigBlueButton hosts/hubs around the world. Wondering if anyone has an interest in joining the BigBlueButton issue queue, it is pretty active. https://github.com/bigbluebutton/bigbluebutton/issues
