So has Google Meet and Hangouts. So was Skype, when I used it about 5 years ago.
Perhaps I'm just used to them as a remote worker, but they were never all that janky to begin with. Or, rather, more janky than the other tools available at the time.
Right. I've worked almost only remotely for several outfits over more than ten years although conveniently I am currently unemployed. I have used WebEx, Skype, Hangouts, Slack's built-in video conferencing, Zoom and I'm sure I'm forgetting others. If you have a sane setup all of these work fine.
I hadn't used Jitsi until this current situation meant friends wanted to "meet up" drunkenly on Friday evenings but it's the same.
The main obstacles are hardware. The cheapest correct working solution for a single individual participant is a headset and a webcam. Can you use lapel microphones, or (as two of my Youtube creator friends do for Friday evenings) sit in front of a huge professional microphone with filters? Yes, yes you can but that's not for most users. Can you plug a high-end SLR that's focused dead on you into a converter and stream that instead of a webcam? Yup, but again most people either don't own an SLR or don't want to set it up just so they can be a bit clearer and brighter when drunk.
And the thing about hardware is that we abstracted this away entirely. Zoom doesn't have different hardware support from Hangouts or Skype or any other tool.
"Which VC tool should we use for this meeting?" is a bike shed discussion at the best of times. Chances are good either you didn't need a video conference at all, or any of the tools would have been fine.
