Interesting examples. I ask this question because the author tries to distinguish between "government or other large-scale organized action" which can be censorship and "cultural pressures or other non-state action" which can't be. To me these examples show that this distinction doesn't make sense.
What do you think of… say that a large political party enacts a law and uses state apparatus to censor something? What when a large political party uses its size to push publishers to form a self-censorship body like the CCA (mentioned in the text)?
The boundaries of the state are blurry. Political parties are IMO in the blurry zone. That doesn't mean that the state has no boundaries or that distinguishing between state and nonstate is always meaningless, it means blurry.
But I'm not saying that the distinction between state and nonstate action is meaningless, I'm saying that the distinction between "large-scale organized action" and "non-state" action is meaningless.
