I don’t want my OS to innovate. I just want it to be reliable. I can say this for MS, I haven’t seen a blue or any other color screen of death for, God, a decade? I’m pretty happy with Windows these days.

I disagree. DMs are most certainly a core use-case. I would argue that it’s a part in parcel feature for any group/voice chat app. DMs have been a standard feature in every major voice/video app, group or otherwise, for over 25 years.

I’m might be being dense but… Still: why would an optional feature be a dealbreaker? You just restated, you didn’t address the confusing logic.
