I am a little more lenient with this for multiple reasons.

First and foremost is that the Chinese are very much against any outside influence. Any attempts by foreign pilots to point out safety issues or potential violations are dismissed as irrelevant. You are a foreigner and thus do not count. You are not considered a valuable resource and they certainly do not really care about your experience or expertise. All the Chinese carriers care about is there is a warm body in the left seat. (At my company a foreign captain was called in to discuss why he did not follow a first officers instructions even though those instructions were incorrect and a violation of operational procedure. In the company's opinion, disregarding the first officer, even if he is blatantly wrong, is considered bad CRM. Your job, in their mind, is to blindly follow the first officers instructions in order to maintain a harmonious flight deck environment. Clear evidence IMHO they do not care about your experience and expertise). In most western and probably most Asian carriers, if a crew member, regardless of background or nationality, points out recurring problems then those problems are taken seriously. Not so with Chinese carriers. Given the recent uptick in extreme nationalism in China this problem is getting worse, not better. When clear issues are repeatedly ignored, a person is more likely to take extreme measures to get them noticed. If a clear process were in place to address the safety issues, through the company, aviation authority, or pilots union, I would take more issue with posting the videos on Youtube. But the Chinese have made it very clear they do not care about foreigners raising issues of safety.

Second - Youtube is officially banned in China. The consequences of these videos being placed on Youtube are different than they would be in everywhere else in the world. If they were placed on Baidu then it would be a different story.
