Any app in which I can type faster than the characters appear has deeper issues than scaling.
No it’s a centralized SaaS IM/chat platform with a very slow web client and no native clients, because it’s not a standardised internet protocol surrounded by a healthy ecosystem.
All of that and they don't have Enterprise contracts with SLAs!
(I'm talking about Discord)
Here's some data to back it up:
Slack's uptime is 99.95% from August to October[1]
Discord's uptime is 99.85% from August to October[2]

In the last 3 months our team has had to (against company policy) fall back to Discord to be able to do our daily meetings about 6 or 7 times.
I wouldn't run Discord on a large company either, but not for stability's sake, but because their (free) screen sharing is possibly the worst if you want to share a desktop rather than a game (it is very much optimized for low delay, and the downscaling makes text unreadable).
