Discord has a huge image problem. I won't touch it with a 10ft stick or even mention it in a professional environment. Besides that it's very annoying that it's a complicated mess that has no real focus.
It's also been latched onto by a lot of articles about the alt-right/Charlottesville, they were apparently using it for a while before they got banned there - and Discord have been subpoenad and things. Nothing that's Discord's fault (actually I don't think it's even encrypted?) but I can see why it'd get a bad look professionally based on that sort of coverage.
Because it's aimed at gamers?

It's a chat and VOIP system, seems to do those both very well. Not exactly complicated.
