In response to Joe Biden and the White House enabling ActivityPub federation via Threads, a number of people asked: “Why didn’t the White House just self-host their own Mastodon server?”
Here’s some very basic musings on what it would take for that to happen. and what some of the hurdles are. Don’t consider it a definitive answer, but a jumping-off point.
Personally I think the biggest hurdle will be moderation and defederation as it pertains to the first amendment. I believe there was already a supreme Court case where blocking a user on Twitter (from an official govt account) was deemed unconstitutional. This precedent might mean a govt instance is not allowed to defederate with any other server unless they defederate with all(?) This is pure speculation on my part, but I can guarantee it would go to the courts.
I think it would make sense to allow blocking users and entire instances that are very clearly not American based and thus don’t have the same rights here, but obviously should be open to all Americans since we’d be paying for it, presumably.
