Exactly. I moved to Discord for VoIP gaming from Ventrilo which was proprietary, centralized, and subscription-based. It also had terrible latency. I moved our entire gaming team of 30 people to it. Mumble already existed, but it lacked a few pros Ventrilo did not have. Discord had so many pros that it outweight the cons, and on top of that: the main con (our privacy / data gathering) is practically invisible.
