This is not a comparable example. It only relates to the possibility of conference content being intercepted. The linked article's concern is over every client machine which has the software installed being exploited. This is not something possible (or at least anywhere near as likely) with browser-based conferencing. And zoom really only seems to offer this as a last-ditch option, the vast majority of users I'm certain ending up installing the software. It's something which I think has received far too little attention amongst the recent security focus over zoom. How traffic is routed is a bit of a red herring if you ask me. The galling thing is how the web community put a lot of effort into figuring out a sensible security model for apps' access to webcams and microphones, and the first thing popular services do is lead people to completely circumvent that and grant permanent high level privileges with seemingly little thought.
