Sometimes, when analyzing bias, it's more important to pay attention to what isn't said, but to what isn't ever mentioned.
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.
