Yes, the censorship continues on Twitter. BUT it is no longer done by Twitter, but from outsiders in the Fed Gov, some universities and NGO organizations. They have back door access.
I am speaking from personal experience. It is certainly still going on.
I try to post a link to a truthful article from a source that they disagree with. I hit “send” for the tweet, up pops a window asking “Save or Delete”. With no explanation. Most of the time I still select save.
We certainly don’t have freedom of speech that is designated by the Constitution.
