It's literally a list of well-run servers. Do you not see how you're attempting to 'take away choice' from the proprietors of the list by telling them who they must list and what criteria they must use for their website?

You're perfectly capable of doing what they've done. Go spend the time to curate a list, put up a simple little site, and make your own decisions. Nobody's stopping you. That's the point of federation and independence. You get to do what you want if you have the follow-through.

Admins likewise can do whatever they like. They can choose to federate with threads or to not.

Personally, I think it's a little shady to run around shaming people who put their time and effort into projects and insist that they must lick Meta's boots. Little bit suspect.
