While this is true - you have to look at the competitive space also (not just Slack). My previous employer forced us on a hosted HipChat. Absolute garbage. laggy; crashed often (sometime taking down my host) and worst of all randomly deleted chat history - so if someone sent you something (important) you may or may not be able to reference it later. Absolute garbage. Left that company (a fortune 50) ~roughly when Teams began rolling out, and my coworkers complained to no end (Slack -> Teams migration happened roughly when i joined). I still complain about Teams - but outside of raw IRC Teams is by far the best messaging App I've used at work. (I do also run slack/discord for personal groups/projects, though nothing at crazy scale).
