Actually, the German government was one of the first public entities adopting Mastodon as a secondary communication channel when shit hit the fan with regard to Musk and Twitter:
I was researching a fire the other day for work, just wanted to verify basic facts. Local FD posted incidents on Twitter. Nope. Couldn’t manage to view it. That’s bullshit. They absolutely should not use it for that reason and to boot helping a megalomaniac make money.
It is a closed system. I tried to look at a company's news the other day, they post it on twitter/X/musk-vanity-project.com. If you're not logged in, you cannot (as far as I can work out) get tweets in chronological order any more. They DO have tweets made in the last few months. But I'm seeing 2019/2020 for pages and pages.
If you're not a user, that site is entirely useless now. Better to just wait for businesses to realise this and GTFO to a proper website. Not this Mickey Mouse toy of Musk's.
