Having used Teams, Zoom, Skype, Google Meet and Jitsi, I'm having a very hard time understanding why people go through the pain of Teams, Zoom or Skype.

Jitsi and Google Meet don't employ any dark patterns, they are fast, they are reliable, they are easy to use. (I do use them only in Chromium.)

Zoom desperately wants me to download their client, even going so far as to require multiple failed attempts before showing the button to join using the browser. Then it wants me to complete a CAPTCHA before letting me join. If I do use the client it opens several separate windows and asks if I want to join using desktop audio. (Of course I do, and if you still want to ask please keep it in the main window.)
