I don't think Zoom "beats" anyone in UX, especially with the dark patterns. They're just popular. I've seen countless times hundreds of people unable to activate the "Computer Audio" option on company-wide meetings because it's in a secondary tab with zero-affordance. Recently they made it very hard to find the "gallery mode" icon (you have to hover a dark area). They also make it borderline impossible to open it on the browser, forcing multiple reloads or whatnot (the method it changes all the time). Honestly Jitsi, BBB and even Teams are all better IMO.

One of my pet-peeves with the zoom UX is that it always switches to full-screen mode if someone is sharing the screen. This is particularly annoying if you are also using the participant or chat windows (because there's voting or chat messages etc.) and if you are switching between different presenters (meaning it switches again and again to full screen). Why can't it respect my decision to not have a full-screen window?!
