Their client software locks up my machine every other day. You can’t screen share on wayland. My coworker can’t run a build while on a zoom call or his machine just dies. The UI has never scaled properly on my displays. The zoom icon is distorted in my task switcher. You can’t use zoom in the browser. It’s a lot of little things that add up. I’ll admit I’ve never used zoom on Windows. Perhaps they've invested most of their effort on that platform. And credit where it’s due, when the video calls work, they work as well as any.
