i wouldn't be so sure. I know I move in privacy and "anti big tech" circles, but I (and a lot of people I know) am moving a lot of my personal/recreational internet time to rss feeds of personal websites, mailing lists, and Mastodon. And there's a fair bit of discussion and small but growing use of private and very small group federated Mastodon hosts.

Having said that, very little of that is being done by the sort of people who'd host it on a service like Dreamhost.
