Wrong. Censorship involves a government. This is a private transaction between two willing parties. There is already a device on the market that strips objectionable content from movies as they are being played. The courts have upheld the legitimacy of this device. The rest is just splitting hairs, and it’s only a matter of time before we can all pick the level of filth we’re comfortable with in our entertainment— a right we’ve been deprived of for too long.

[Sto Zvirat]

If a religious group didn't like a newspaper and they went out and took all the prints and covered up certain words and removed certain stories and put the papers back on the rack...that wouldn't be censorship?

Definition of CENSORSHIP 1 a : the institution, system, or practice of censoring b : the actions or practices of censors; especially : censorial control exercised repressively
