I don't know what twitter is like, but if you "hover" over a video, it automatically starts playing, and I am pretty sure that would qualify as a "view", but it really isn't I dont think.
I think Mr. Carlson is probably still somewhat popular, but like a lot of people who assume they are bigger than they are, once they switch shows, platforms, etc., it is realized that they aren't.
However, there will be someone who takes his place and is the next "Tucker Carlson" or next XX person.
