I just saved the day for the Sagemath dev meeting an hour ago by getting us to all use Jitsi instead of the broken zoom. Most of the other participants hadn't used Jitsi before, so it was a nice opportunity to introduce them to it. I would also add another point to your list above, which is (3) Jitsi is open source (APACHE licensed -- https://github.com/jitsi https://github.com/jitsi) and you can use it without creating an account or self host it. It seems to be a great project that deserves more popularity and support.
