I think the issue is that your are expecting a perfectly seamless, Reddit-like experience, with all the admin work done for you but also always done to your satisfaction. That isn’t what the Fediverse is about. It’s more of a DIY ethic than a “The admins suck but this is all we have” like on Reddit.
I’m also not sure what you’d need to “migrate” to a new instance other than yourself. Karma isn’t super relevant here.
My main account is on Beehaw, which has very rightfully defederated with some other instances. When I log in using accounts on other instances, I don’t see a massive amount of missed content. In fact I’ve seen so little of interest that I’ve stopped looking, it’s not worth my time.
The jokey post is true. The difference is whether a user sees this as a bug or a feature. Many of us see it as a feature. If you see it as a bug, maybe Lemmy isn’t for you.
I also don’t want to see the Fediverse “succeed”. Both Reddit and Facebook were great for a while, then they “succeeded” and enshittification began. The Fediverse is fine how it is, it doesn’t need to become the most popular thing on the internet in order to keep my interest.
