doh, I forgot about voice chat.

People should also be able to create their own servers without worrying about technical details, and again, without directly paying for it.

I think this is the real reason why Discord is so ubiquitous nowadays. I remember back in 2017/18, it was really only (PC) gamers who used Discord - because your average PC gamer is somewhat more tech literate than the general. Nowadays, every community and their mother has a Discord server.
