Tencent for one. Also, why would you move if the app is not much different? A migration is costly and Discord doesn't offer anything substantial over Slack.
I see most companies now gravitating towards MS Teams instead. As it comes for free with O365 and performs adequately. I still prefer Slack with its joinable channels and higher screen density but I have to make do with teams as the company I work for is also one of those who have dropped Slack for Teams.
one could just as simply make the inverse statement without qualifying it: "Why don't more gamers simply use slack? Discord is slack for zoomers" - although having used both, the feature set is not identical, so ignoring the obvious generation predjudice, both statements are equally invalid.
We recently tried to use Discord to set up community servers for our users. Turns out that Discord has an extremely sensitive bot detection filter which made it hard for a lot of users to get into the server in the first place. Of course, we can’t turn it off and Discord wasn’t interested in helping us, so we had to scrap the integration and find another solution.
TLDR: Wouldn’t recommend Discord for a professional use case
