It is less about recommending "good" content, but more about cutting out the unwanted stuff. I agree this is very dangerous territory. I'd even say filtering at all is dangerous.
That goes not only for state-mandated suppressing of content, but also for YouTube and similar services filtering content that does not fit their idea of a "family friendly" environment where they can sell the most ads. The motivation is different, the result is the same.
Right now, this kind of filtering could suppress news from Ukraine that YouTube considers too shocking. Only a few days ago, a video about the reporting career of Seymour Hersh was blurred out on YouTube, the images from My Lai seemed to be too much.
