Chill, you’re not the only one here.

VoIP in a mainstream messenger is something that most people use nowadays to avoid calling people from their SIM cards which costs them much.

Video calling too is something I personally use too especially on iMessage or Telegram.

I’m a software engineer, I appreciate some old school things that work perfectly well like ICQ or Vim or emacs or working only with shortcuts. But you know what’s also a shortcut? Not having to use 50 different messengers just because this one doesn’t have VoIP and I can’t bring my friends or my mom here but I can bring only my nerd friends”.

This is all business and target audience oriented. You are not the only target audience out there and especially when you don’t demand from a messenger to be able to have VoIP. Even Instagram has VoIP these days. A photo-video-media sharing app. Let alone a messenger.
