Though creating a lemmy account is not that complex. Typically all you have to do is fill out a form on the websiten instructions included. The problem there is not the tech literacyn but the willingness of the people to even interact with systems they don’t know, like finding a home instance or understanding the concept of the fediverse. Most people could create a lemmy account, though also most people wouldn’t.

Spot on, it feels complicated because they don't understand what's being asked. I've said this before previously, but most people have no concept of frontends and backends. For most people, Twitter is just something that's on their phone, and it uses the internet to see what other people have in their Twitter apps on their phones.

Because internet usage and software generally is like 99.999% commercial, even the idea of closed and open source probably doesn't make sense to a lot of people. "Check out Mastodon, it's like Twitter but anyone can host it" would mean nothing to the average user. I'm on the absolute lower end of tech literacy in this community, so it's constantly apparent how much my Lemmy friends overestimate the general population.

Edit: To be clear, I say that non-critically. The tech industry has made it so astonishingly easy to interact with incredibly complicated systems, but they exploit the resulting ignorance for profit and market share because it severely limits our agency to choose something less antagonistic.
