There's a gazillion videos all over youtube criticizing, mocking, and calling out the Chinese government for all sorts of repressive activities. I'm confused as to why people would think youtube is bothering to sensor those two characters in oparticular as opposed to something much more likely like spam/bot filtering or channel word filtering. I'd think the Chinese Gov would be much more animated about videos like this: https://www.youtube.com/watch?v=r9AvUuEPgvA https://www.youtube.com/watch?v=r9AvUuEPgvA or this: https://www.youtube.com/watch?reload=9&v=S3RzKKfNkTk https://www.youtube.com/watch?reload=9&v=S3RzKKfNkTk or this: https://www.youtube.com/watch?v=Y4TReo_G74A https://www.youtube.com/watch?v=Y4TReo_G74A or any of millions of other videos. i can find plenty of negative comments directed at the chinese communist party in comments all over youtube.
