While Jitsi is open-source, most people use the platform they provide, meet.jit.si, for immediate conference calls. They have now introduced a “Know Your Customer” policy and require at least one of the attendees to log in with a Facebook, Github (Microsoft), or Google account.
One option to avoid this is to self-host, but then you’ll be identifiable via your domain and have to maintain a server.
As a true alternative to Jitsi, there’s jami.net. It is a decentralized conference app, free open-source, and account creation is optional. It’s available for all major platforms (Mac, Windows, Linux, iOS, Android), including on F-Droid.
I’d personally prefer they didn’t implement any KYC-style identity verification at all in the first place, but it’s not my service or project and I’m not a paying customer, so my preference is largely irrelevant to them. But that said, I didn’t intend the comment to be damning, or even a particularly harsh criticism, just thought it wad an odd choice.
If what you are saying is accurate, and there aren’t better options, I at least understand that choice a bit more. If they feel they need an identity provider for whatever reason, they should obviously choose the one they feel best fits that need. And as others have noted, different servers and instances can be spun up or utilized. Users can choose to utlize whichever fits their needs best, or none if none of them fit.
Your other point is well taken though that it may be a gap in the marketplace. Sounds to me like a need waiting to be filled. I recall reading about some decentralized blockchain solutions for this sometime back, but do not recall the specifics. I haven’t followed along because it didn’t seem relevant to my personal or business needs at the time.
If anyone else knows of alternative options that may be better or more privacy friendly, I’d certainly be interested to hear about them. And would chip in funding for any good FOSS projects that might seek to solve this problem.
