It’s all relative.

More private than Google or Meta? Hell yes.

Suitable for whistleblowers and journalists reporting war crimes? Nooooo.

But Jitsi you can run it yourself and you should.

Understand that the public instance is provided freely as an alternative to Google and Meta, and whilst I agree encryption should be the default - it does add overhead for something probably running on donations.

Yes

Short answer is yes, Long answer is by how much depends on tos and what keep and use, and really what you consider risk.

Before things were relatively mild, picture your jitsi meeting is a public cafe with a security cam. Someone would need specific info to see you at the cafe or get footage from the cafe owner. Now with ai training anything said or displayed could be used as training. Voice, speech patterns… Its a wild scale best to find reputable companies or selfhost

Yeah, kind of. I doubt they analyze what you say on it but they could do it, technically.

I would recommend using a self-hosted instance if you can, it’s very easy to set up with docker.
