This article is a bit narrow in scope, e.g.

> "Horrified by Stalin’s Soviet Union and Hitler’s Germany, Orwell spun a tale that continues to color how we picture state censorship in controlled societies."

Orwell was equally 'horrified' by the British Empire's imperialist practices, which he documented in then-Burma. See "Shooting an Elephant" for example:

George Orwell: "I had already made up my mind that imperialism was an evil thing.... I was all for the Burmese and all against their oppressors, the British."

Now, if you want to experience censorship in the 'Western liberal democracies' today, just replace "the Burmese" in that quote with "the Palestinians."
