A big issue with the 2022 signup wave was the influx of new Masto websites, run by new admins. The subscription model of ActivityPub meant they were mostly contentless, and they weren’t seeded by knowledgeable users. People needed to understand the basics of federation to find anything because nothing was being syndicated on those sites.
And then a bunch of them shut down when admins who were ok hosting hundreds of like-minded users suddenly had thousands of generalist users flooding their sites.
It was major human infrastructure failure.
And that was as a whole bunch of tenured users started getting hostile over people not adopting the idiosyncratic nettiquite of the was-niche-only-yesterday space. The server blocks started rolling out, and people needed to understand the idea of “federation” (and, apparently, “the Internet”) to understand why they were being “denied access” to the cranky people, trolls, and unmoderated spaces.
The truth is, most people don’t like the internet. They like the simple, streamlined process of just being owned by corporate interests. Walles gardens work for them in a way public parks never will.
