Censorship: the practice of officially examining books, movies, etc., and suppressing unacceptable parts.

Isn't the suppression of "unacceptable" information the stated goal of the right to be forgotten?

News organizations can still publish articles about someone who invoked the RTBF, but nobody will read it because it's impossible to find.

In the bureaucratically definitive sense it's technically not censorship, it's just using a characteristic of the internet to make it censorship. At least, that's the writing on the wall.
