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.
That's the only reason I've used it for in the past. Following news agencies and NGOs.
Now it works the same way with mastodon.
