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.
That sounds like such an incredibly toxic environment. That goes well beyond the kind of infantalization I initially thought, and is well into deeply controlling territory. You need support! Social support, and structural support. Do you have some? Friends? Support groups? People you can lean on, and trust to provide some kind of safety net?
That kind of abuse is scarring. I highly recommend grabing copies of books like The Body Keeps the Score and Complex PTSD: From Surviving to Thriving. There are audio books for each, which are really good, and they're available as epubs if you're ok with digital books. You should grab copies any way you safely can.
You deserve help and support. We all need it to grow up and survive. It can be hard to find, especially when we're hurt and suffering the injuries of abuse. We will often find the wrong people, and find it very difficult to identify and trust the right ones. But there are people out there who will respect, love, and nurture you. If you haven't found them yet, look for them, and don't stop until you find them.
They will change your life, and in ways you will never imagine. I promise you.
