Patreon, forums, Discord, Facebook, Instagram and so on are all centralized.
With the Internet of the 90s, discussion happened with decentralized Usenet (owned by nobody) with more-focused discussion happening on mailing lists (literally owned by whoever was smart enough to get Majordomo compiled and running).
Email was handled by individual ISPs or other orgs instead of funneled through a handful of blessed providers like Gmail.
Real-time chat was distributed on networks of IRC servers that were individually operated by people, not corporations.
Quickly publishing a thing on the web meant putting some files in ~/public_html, not selecting a WordPress host or using imgur.
Ports 80 and 25 were not blocked by default.
Multiplayer games were self-hosted without a central corpo authority.
One could construct an argument that supports either way being better than the other, but the the Internet of today is not the same thing as it was a quarter of a century ago.
(Anyone can make a "discord server," but all that means is that they've placed some data in some corpo database that they can never actually own or control.)
