So today I clicked a twitter link because companies like to use it for official announcements, only to be greeted with a login page. Was annoyed then I remembered nitter exists. It just prompted me to install Privacy Redirect which I should have done ages ago.

Looks like twitter waited for the reddit API changes to do push this change to try to do it under the radar.
They could easily have their own websites based on Mastodon or Lemmy, not federated with anything.
They could also just use RSS feeds for one way notifications.
this is true, but that would require their audience to know about and use RSS.
People had to learn to use Twitter too, they can learn to use a feed reader. Or they can just read a website. It used to be common practice to just go to an official website, and optionally subscribe to its feed as well. Browsers used to make it super easy by prominently displaying a button that showed you that the website has feeds to offer.
Or just use RSS.
