This is why the internet sucks now. Nobody maintains their own websites anymore. These days everybody just posts everything on the same handful of centralized megacorp websites. Social media killed the golden age of the web.
E-mail, too. You could have all the latest security features to confirm you're legitimate, but based on the simple fact that your message volume is low (ironically enough), messages you send with your server will often get filed under junk by default.
This is essentially a very fancy forum. I wouldn't expect corporations or politicians to be posting here. Maybe they could host their own instance and federate. In principle, that would mean they're paying for their own hosting and have control over their message being altered.
But yeah, I agree. And there's no excuse for it really. Sure a regular person only posting to a single social media makes sense, but anyone that has staff should be able post to their own website, issue a press release, post on Twitter, Mastodon, Facebook, Blue Sky, Reddit, etc. I mean once you have the statement finalized it's just copy & paste to get it on all platforms. It seems bizarre that they don't do this.
My first reaction was that he was hacked. It wasn't on official letterhead, there was no other announcement, and the president didn't immediately make another tweet/x/whatever.
I don't think I'm alone. Typically when something big like this happens, I get 5-10 news alerts within minutes of each other from various sources. The alerts were slow to roll in today.
