If your company uses discord as a tool to communicate, it gives the message that it's like a game to you, that it is not serious, that you are relaxed,etc..

Certainly not the right register for serious stuff like an IT company, tax company, weapons, etc...

And it's not just semantics, the app was built for gaming, it has features and design choices built for that, one of them being kid safety. Not a corporate tool like slack.

If you are into that great, but it's what it is.
