> Messages, Signal, WhatsApp, and their cohorts all share the same fundamental two-level design: a list of chats, and a single thread of a messages within each chat. WhatsApp and Telegram both got “rooms” inside groups (“communities” and “topics”, respectively) to organize groups around topics/subjects, pretty much like Slack and Discord. Hard to justify a whole new app just to mimic features all other apps, with people already using them, have or will eventually have.
