I've been using chat clients since the '90s but for the life of me I can't figure out how to use Discord. At least for me, the interface is effectively unusable. It was bad enough for me to attempt to use such a proprietary service, even if I couldn't figure it out. And then I learned about all the shady practices, such as going after third party clients, seemingly random deleting and/or locking of accounts, requiring phone number, and now I just refuse to touch it. I am clearly not Discord's target audience.
