The real question is: How in the world did Ventrillo continue to exist after TeamSpeak came along?
Vent was an object lesson in hostile UX. It sounded like shit, changing any kind of setting (even basic things like individual volumes) was a a gymnastics routine, and mics constantly clipped despite settings.
Unpopular opinion, ventrilo was better than team speak. It didn’t sound like crap especially when you had good server codecs and it was extremely easy to use and lightweight.
I don't think that's unpopular at all, I only ever used vent in highschool and uni, some of the groups I ran with even went back to vent from TS becauae of the sound quality. It was simple and easy to use and pretty much everyone had it.
