That's what I saw as well. But I talked with some founders and they told me they have some trouble with discord as well. Like there are a lot of noise, it's not designed to handle multiple threads with different users, when you wanna do 1-on-1 chat you need some data on users (how often they use your product, from what country they are etc).

I've seen the same with Matrix as well. (Also IRC, though fewer and fewer people seem to be using that.)
