"I didn't want the headache of having a publisher reviewing everything I wrote in advance"

This quote by Mark Millar speaks with the flexibility of being an independent author. He is revealing his choice for not having to go through the procedure of having a publisher review his work prior to it is launched. This might be viewed as a kind of censorship, as the publisher might not agree with the material of the work and might request changes to be made. Millar is likely expressing his desire to have complete creative control over his work, without having to fret about somebody else's viewpoint. He likely values the freedom of having the ability to write whatever he desires, without needing to stress over another person's opinion. This quote speaks with the importance of creative freedom and the worth of having the ability to express oneself without fear of censorship.
