If A = RationalWiki might have perhaps misrepresented Roko's basilisk
B = I don't think that EY gets to complain that people learn about it from RationalWiki
C = he has censored any discussion about it on LessWrong for year
The literal denotation of your post is "A, but C -> B", but it seems to me that mentioning A in such close proximity to C -> B is a (perhaps unintentional) Dark Arts way of communicating C -> A.
C does not lead to A, but C does lead to A', where A' is "many people get their information about the Basilisk from RationalWiki's misrepresentation of it" (Banning discussion leads to good information being removed, increasing the visibility of bad information.)

I guess there'll be a fair bit of traffic coming from people looking it up?
