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.
I just checked a random news article and embedded tweets seem to be working still. But when you click the tweet you get taken to the login page.
I don’t know why they bother embedding tweets. They always quote the tweet anyway, so you end up reading the same bit twice.
