At first glance that sounds reasonable. Nobody wants YouTube or anyone else to recommend bad information. And almost everyone agrees that phony miracle cures, flat earthism, and blatantly false claims about 9/11 and other historical events are undesirable.
But if we stop and seriously consider those words, we notice a couple of problems.
First, the word "recommend" is not just misleading but mendacious. YouTube obviously doesn't really recommend anything. When it says it does, it is lying.
When you watch YouTube videos, the YouTube search engine algorithm displays links to other videos that you are likely to be interested in. These obviously do not constitute "recommendations" by YouTube itself, which exercises no editorial oversight over content posted by users. (Or at least it didn't until it joined the war on conspiracy theories.)
The second and larger problem is that while there may be near-universal agreement among reasonable people that flat-earthism is wrong, there is only modest agreement regarding which health approaches constitute "phony miracle cures" and which do not.
