Hangouts was fine
What's equally crazy is how Google killed / butchered / neglected / abused Hangouts (which most of the early Slack adopters had via G Suite) and those same companies are now paying to use something that does 99% of the same thing. Slack is a glorified .gif sharing network and I seriously doubt it contributes in anyway to effective and productive working.
Just like open plan offices - it's noisey, a distraction and should be eliminated immediately.
