So I wouldn't get all the tinfoil over this matter, I would probably disable Facetime if I were most people though. Then it's likely to only be an issue of audio being streamed, much less horrible than inappropriate video streaming. I would hope they roll out a server-sided fix initially. "If calling user, if user ads themselves to group call, hang up group call" or some silly logic. I rather see that first, and then the client-side fix.
