For example, it's easy to be factual and accurate when you can pick subjects that don't touch anything in a list of sensitive spots.
Another thing to keep in mind is the intended audience. If they don't expect more than, say, 0.1% of the Chinese population to watch that content, they might relax the censors. There are half a dozen cases of Brazilian rock records sung in English where the international version wasn't censored, but he Brazilian version was very tamed down.
I will admit that I haven't watched their content, though, so feel free to give a rebuttal.
