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.
