Each has its own strengths, so it's all about finding the right fit for your needs!
Anything self hosted would require dedicated staff and the upstream should provide a friendly development environment that could accept code contributions from all the companies that use their product. Maybe that is Jitsi based on other threads here? There seem to be mixed experiences. And that probably depends on how many people would be simultaneously using the platform as well as how many developers are going to contribute up-stream. An example of this concept was OpenStack. Many companies eventually contributed up-stream but those contributions ramped up a little late and many people already had a sour taste in their mouth. People still use it but the adoption is not what it could have been.

Take google meet for instance. There are already two versions of this app on the play store. One is "google meet (original)" and the other is just "google meet". The weird thing is that both of them are regularly updated, and the "(original)" app was last updated just a week ago.
As for alternatives like Jitsi, perhaps I can get it going, and perhaps a few people would join for a few weeks. The interest will slowly die out as people go back to what they know - zoom or teams. My mother in her 70's uses zoom to collaborate with others on some work that she does - they understand the privacy issues but they simply won't accept the hassle of changing to something else. Not unless zoom does something really bad.
I'm assuming you are referring to concerns like laid out here [0]?

I believe they invested heavily into designing their own audio/video protocols based on UDP but with specific enhancements.
Grateful if anyone here as specific knowledge in this area and is willing to share.
