I saw those articles. Quite a few talked about how Zoom was weirdly insistent that they had end to end encryption (which they do not), and they added some disturbing privacy violating features to the desktop client which they're oddly pushy about, also their privacy statement wasn't exactly reassuring. All red flags, but strictly speaking they don't really impact the security much (they might do god knows what to the metadata, but to my knowledge, that's the same with most alternatives).

The one truly sensitive issue is the zoombombing, and I haven't been able to figure out whether that's truly a security bug or if zoom is just the biggest attack surface and has some terrible default settings.
