How the Zoom macOS installer does its job without you clicking ‘install’

As someone who's never used or seen Zoom in action, what's pulling people into Zoom that's not already available in other tools (Hangouts Meet, MS Teams) and even works without installing anything (such as Jitsi)?

Based on what I've seen, there's just so much hostile behaviour by the company (including lying about meeting HIPAA e2e requirements!) and the fact that their _official client_ had parts removed by the macOS malware removal tool that I just don't get why people still consider it as an option. If it were the only "just works" tool out there I'd understand, but there's plenty of competition in this space.

I've personally began using the Jitsi server the local student network association has set up and it's been working like a dream. You can even share a window to others (which I didn't even know browsers had support for) for presentations and such.

The meme that HIPPA requires e2e is so ridiculous - it is pretty clear that very few people actually deal with HIPPA stuff.

Zoom (if you need HIPPA) can set you up with it - but you WILL lose a bunch of features (zoom by default has features that are not HIPPA compatible) - so make sure you need HIPPA before paying for it.

If anything medicine is almost anti-e2e. Everything is copied and copied between one system and another (billing, lab systems, imaging systems etc). Seriously, medicine is in many cases very fragmented, so the number of medical practice groups that need copies of your details / visit details etc is high just to bill you (and you may end up with 5 bills for one visit - which may be 4-5 systems behind the scenes).
