@Infrapink The White House would probably love to set up its own Fediverse instance, but first they’d have to harden it against hackers, ensure it passes accessibility and archival requirements under federal law, and a whole bunch of other stuff that might well involve forking the server software to make sure it’s done right.
There are a LOT of federal laws governing how official websites look and behave, and a lot more bureaucracy to ensure it’s been done: https://digital.gov/resources/checklist-of-requirements-for-federal-digital-services/
@raven667 @mighty_orbot That applies to government ministers using non-government social networks already. There was a court case a while ago which ruled that members of Congress aren't allowed to block people on social media (but can mute them).
I don't believe it's a violation of the First Amendment to restrict social.whitehouse.gov to White House residents and employees; doing so would obviate a whole bunch of potential issues.
