Yeah, I'm honestly a bit surprised because I personally would agree with Zoom that what they're doing is "end-to-end encryption." (Maybe it'd be nice if they had a "mandatory e2e" checkbox that you had to uncheck to get a dial-in phone number, but, obviously when I call a number by phone I know there's no e2e going on.)

I think the pile-on is mostly because finding security problems with Zoom is the cool new thing to do. There's been no shortage of genuine security problems with Zoom (and an apparent lack of security culture) but I think we've now gotten to e.g. "you can use Zoom to trigger a Windows design flaw that's been around for years" or "when you set up a meeting anyone can join, anyone can join the meeting" or whatever, and the media is happy to pick that up.
