In theory, I agree, but in practice, I have used #Ring, the earlier version of #Jami. The experience was so poor that I can no longer get my in-person contacts to try anything that is not #Facebook / #Instagram / #Zoom. And that's without ever trying the #videochat functionality ... we only used text chats and it was still a really poor experience.

I've heard it got better, but of course, none of my in-person contacts will try it again. This also affects apps like #Briar and #Session.
