Zoom through a browser only. As for the rest, they may have "analytics" (spyware) but are there any documented cases of any of them acting as an X11 keyloggers or covertly screenshotting the users desktop? Those are the threats Wayland asks us to fear. And Wayland won't protect us from the rest. If Firefox or Audacity phone home with reports about what I'm doing with those applications, Wayland won't stand in the way.
