If somehow alternative news sites are banned or as been suggested that Google or Facebook act as censors determining what is "fake news" then the Constitution will have been stood on its head, completely subverted and we will have become the dystopian world George Orwell wrote about in his novel, 1984.
The US will have descended into absolute tyranny.
As to the question why did it have to be this way? Well we weren't vigilant. We took our freedoms for granted. We let it happen. The next question may very well be can the damage be corrected?
I suggest re-reading the Declaration of Independence.
