I think the main problem I (Along with many others I know) have with zoom is that it basically requires you to download and install something before you can join a call. Obviously you can call in but if you want good quality video you have to download their app. Being forced to download the Brave browser in order to join a call just seems like blatantly unreasonable bar of entry. If blocking website ads wasn’t enough for me to download the browser, video calls with only other people who have download the browser certainly won’t be either.
