There is a fraction of people who agrees with it. Otherwise it wouldn't be there.
But most people dislike, or at least are annoyed by, the censorship.
There are several different kind of dislike. There are people who are opposed to censorship in principle. There are people who find certain rules or mechanisms too ridiculous. There are people who only complain when it inconvenience them.
There are several types of supports. There are a small fraction of people who think that whatever the government does is for the greater good of the country. There are people who are happy when the fist hammers down on contents that they don't like, e.g. porn, anti-patriotic speech.
I'd say, anecdotally, most people find the current state of censorship somewhat unreasonable, but at the same time, have accepted it as a trait of the Chinese society that isn't going away in the forseeable future.
