We used WebEx a lot at Apple. It was pretty terrible when I first started with a really bizarre client, but when it was updated to the more modern one in ~2019/2020, I didn't think it was so bad, more or less like every other VoIP program.

I still kind of viscerally hate it because I associate it with the boring and useless meetings that the middle-managers at Apple loved to schedule to justify their existence in the company, but that's not really WebEx's fault.

Slack, Meet, Zoom.

Teams tries to be the default chat app and video app and sucks at both.
