there was another "sign in using google" popup in the top right, as well, that I dismissed because email addresses and deadname
anyway if you're not logged in, you can't see:
- any other tweet in a thread
- tweets in chronological order on a profile
- any tweets deemed to contain "sensitive content"
- just random tweets, for absolutely no reason whatsoever
I can confirm that I can't see any of this shit as I deleted my Twitter account a long time ago. Sometimes Twitter shows the tweet, sometimes it locks it behind a log in screen.
