With the browser version, I can just open my browser and point to the URL and run it. Easy.
With a native app, this usually means I'd have to go buy a new computer running Windows or MacOS just to run this one stupid application, because I don't have either of those OSes at home. Of course, I'm not going to do that, which means I just don't use the app at all.
Most non-tech people just blindly drink the poison and install it.
Zoom is not alone in doing this. (Or maybe it's a Windows "feature"?)
If that's what stopped parent poster from uninstaling, that's PEBCAK.
Web applications are generally better, because, as a Linux user, an in-browser application means I get to actually use the thing, instead of not using it at all.
Then you're not most people. This isn't that controversial.
And Zoom does have a Linux version in case you're not aware: https://support.zoom.us/hc/en-us/articles/204206269-Installi...
