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.
