I now see senators in my country holding meetings over Zoom and it's horrifying.

I've been avoiding most things Google, but these days I don't have a problem with colleagues using Google's Meet, because honestly I trust Google more than Zoom. Skype is another popular option.

This is a wasted opportunity for a solution like Signal.org to provide support for e2e group video calls. I'm guessing it's not easy to implement.
