Having just played around with it: It still is; the only difference is that everyone is left "waiting for a moderator" until one person clicks "Log in", and jumps through the hoops to let Jitsi use one of their logins (which is pretty quick if you're already logged in).
Not great, but it does at least give some accountability.
I think it would have been best if they simply shut down their official instance, instead of gating it only to Google/Facebook users.
There's still plenty of other instances out there, and it would give a far less ambiguous message if they just pointed people to community-maintained instances.
Moving to a "we only serve Google/MS users" while claiming a focus on privacy definitely doesn't send out the right message
The beauty of Jitsi Meet was that any URL was a valid room. That was such great UX.
Of course, other Jitsi Meet instances still exist. But this will probably still influence the project's direction.
