> I don't like splitting my conversations over multiple apps

Most people don't. The issue isn't what country I live in (fuck man, I got SMS, WhatsApp, Signal, Slack, KakaoTalk, and I've even forced some people to not contact me through some apps so I could reduce). You missed the actual content of the message about how there is a reasoning for this change beyond Signal. You got to be careful with blame because there are often things upstream that cause things downstream but the fingers are often pointed at what's downstream, not upstream. We can't resolve problems if we only focus on downstream. You have to consider both. I hate it too, because it is the mental version of using multiple apps. But that's the way things are and I want to actually reduce the problems, not run around with a box of bandaids.
