A number of governments (France, Germany, Switzerland, Netherlands), international organisations (The European Union, The Council of Europe, W3C etc), public broadcasters (ZDF, the BBC, PBS/NPR affiliates etc) have set up servers or accounts on the Fediverse.
Please ask public services in your country/region/area to follow their lead. I can do a shoutout on @FediFollows to help get them started.
Musk's Twitter hides all its accounts behind a sign-in page, so it's no longer a public channel.
@FediTips @FediFollows let's be honest here. My country (Morocco) is very unlikely to ever contribute to the fediverse. I haven't seen a single Moroccan Mastodon account outside of my own. Most of us simply aren't very techie enough to know about this stuff, that's why.
