Doesn't "POTUS is using threads for social media" feel a bit like "POTUS is using outlook.com for email"?
Is there anything about the bureaucracy that stops their some small team to setup a Mastodon server on "social.whitehouse.gov" and make this a reality? I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform. Also, none of this seems to be a problem for some of the EU governments.
Maybe I am missing something. If there is someone among you working with the US Goverment or aware of how their digital initiatives work and can shed some light into this?
