No Internet censorship, says Najib

No Internet censorship. Is this really true?
Najib at the ‘Blogging Mindfully and Responsibly’ conference:

Malaysians have to thank Tun Dr Mahathir again for this. When he was prime minister and Malaysia was developing its Multimedia Super Corridor, Tun made the promise to the world that Malaysia would never censor the Internet.
My government is fully committed to that wisdom; we intend to keep his word.

So what happened to Malaysiakini and Sarawak Report in the run-up to the Sarawak polls?
