Slack is an expensive software. I expect performance and yet, I can't find messages, I have a hard time to use slack and run IDEs at the same time, they change the interface and I lost 2-3 days until adapt. If I could save some bucks removing videos, emojis, voice and video streaming, I would not hesitate in do so. You got a fair point on how things work: it's all about communication. You want to stay where everybody is, so the incentive is to capture market, not make a fast software. I think that most of the innovation effort in the last decade was on how to delivery fast.
