Does anybody have a good alternative to zoom that does not do this?

An open source alternative might be Jitsi Meet https://jitsi.org/jitsi-meet/. I haven't tried it though.

Google Duo?

If you would prefer to self host, there's always FreeSWITCH [0]. It can act as a server for meetings. There is a webRTC client called Verto Communicator that seems to work quite well, or you can use SIP clients.

The documentation is a bit lacking, but it's actually a very capable system for unifying voice, video and chat communications – and a whole lot more.

I've been using both Uberconference and Google Meet (G Suite only). Both of these run entirely in a browser without any extensions or applications.
