I also would be interested in some slightly more informative coverage on this question.
I have used jitsi with my team several times now, it worked well, we were happy to find it, thanks! I did end up installing the app, from f-droid. But I admit I was surprised at seeing the notice that said I had to. I had followed news about WebRTC for a while and was expecting at least the option to join via browser.
The same issue has been raised recently re: Zoom, and rightly so. In their case, of course, it’s a closed-source app, which is worth an even bigger squint before agreeing to install it on a phone.
But even in the case of an open-source app that’s on f-droid, installing any app on a phone is always a judgment of risk. A service saying “hey! download our awesome app!” is asking people to take a risk, and not asking in the respectful way that is appropriate when asking someone to take a risk.
Likewise, an explanation like “many cases which are covered” and “better OS integration” is ok as far as it goes … it just doesn’t go far enough as a reply to a person who is reasonably asking “why are you advocating I should take this risk? Why should I advocate to my attendees that they should take this risk?”
That sort of an answer would actually say something about the many cases which are covered, and what’s better about the OS integration. Like, specifics.
It would also be useful to know, even if it isn’t recommended or supported, is there a way on a mobile device to elect not to download the app, and continue via the browser? Is there a way for a meeting organizer to expose that option, if it normally isn’t? As there’s already been media coverage of the same issue for Zoom, it would be great to know what the story is here.
