Since the 90s and 00s, a lot has changed with how internet services are accessed and used.

The problem of "how do I get people to use and fund my server" is still an unanswered one by projects that implement a lot of FLOSS-based services. It's a bit better than it used to be, but if I suggested that my Discord servers try my new IRC system that I hosted somewhere, most people are just going to pass because it's not going to have the level of polish and ease-of-use they're used to from group chat applications.
