An example might be that the government sets up its own very basic one-way tweet-like notification service, something as simple as or simpler than an RSS feed, with the official content accessible directly via a .gov hosted web page.
Whatever X is or becomes, as owned by private interests, is trusted with nothing more than scraping and rebroadcasting the original and authentic source.
A solution with less developer and user overhead ma ybe that government webs host a list of public keys by which any "gray or blue check mark" type of authenticatuon signal capability on any private service can be validated against, and the government can revoke keys at any time if for some reason there's a suspicion that a counterfeit message is being distributed via these private services. Maybe repurpose the creaky old atomic clock time sync radio signal that is deployed almost everywhere as a means to distribute a rotating secondary factor. just old PKI tactics proven to work for two plus decades.
But this approach is still open to exploiting human tendency to trust things that have been trustworthy for a long time, until they aren't. So I still think hosting official messaging feeds directly from a government run server, accessible by any barebones http client capable of displaying plain text with basic paragraph/item formatting at most, is the gold standard.
The current situation, where X or meta or google or even a mastodon instance is entrusted with the entire conduit from human input to broadcast output, is a terrible precedent to normalize.
It looks like all of their tweets are just links to items on the news room portion of their website. If you click around a little there, you'll see that they do have RSS feeds:
So it looks like they're already doing exactly what you suggest: they post official announcements on their website which you can subscribe to using the standard way to do that (RSS), and they also rebroadcast on Twitter by linking back to the original source. What should they be doing differently? Periodically tweet reminders that you can subscribe directly to their RSS feeds? Stop posting to Twitter at all and leave only a message that you can find official news on their website?
Your ideas are honestly great and both of the solutions you presented (RSS->.gov site and public keys) feel like great solutions. I think the problem is that both of those require the general public to have some amount of technical knowledge which is, apparently, a big ask. The first would be a lot easier to present and avoid confusion but it'd still require people to know to go to that site.
For what it's worth though, I think the solution to that is people should have some real amount of education about the function and potential dangers of the internet before getting on it.
