Will you trust its creator and use it?
Unfortunately I don't expect it to get much traction. People will prefer the free audio-video calls, no matter how centralized they are and how much data is stored about them. So I expect the new app will be very far from Skype, WhatsApp, Teams, Google meet or Zoom. And I'm sure my list is far from complete, only in picking the really big ones.
And as the others said:
* not the shadiest companies, by far
* closed source, so they can claim anything
And my answer: most probably no, since the few people I do video call with already have their preferences (or requirement!)
