Wow. You're very much not understanding - I'm definitely not saying it's intentional. It's a take on the "It's not a bug, it's a feature" notion.
I'm saying that signing up for Lemmy not being as one-size-fits-all intuitive as Web 2.0 social media is a net benefit because anyone who tries to sign up, gets confused SO easily, and then frustrated and gives up is not the kind of person we want taking up server space on a Lemmy instance.
