The whole insistence that the fediverse is too complicated is so strange to me. People are acting like you need to know how to federate multiple servers in order to make/read posts. It's been exactly the same experience as setting up an account on any other website for me. The only difference is I had to spend five minutes understanding what an instance and how to find communities on instances that are not my own.
Some people are just fundamentally resistant to any kind of change, I suppose.
