AFAIK, you can't view any tweets unless logged in these days. But the sort of user being frequently blocked likely has multiple accounts anyway.
You can view a single tweet, but it won't display a thread for you unless you log in.
I clicked a link to NYPDs twitter and didn’t have to AuthN. Makes sense too; every org who wanted their content to be fully available to anyone would leave if twitter mandated login
(Although they still use Facebook)
Every single public account I've visited still has the feed in non-chronological order which instantly makes it useless to me. I don't care about a post from my city government in 2019.
But everybody still calls them "tweets" because it was an amazing bit of branding.
