It is good enough, 2019 doesn't mean we don't reflect user behavior.
Not every recommender is a moral agent. Auto-suggest and conspiracy videos aren't the same thing.
And technically, yes, there's not such thing as a non-editorialized recommender, but this feels like a pointless nit since there's a world of difference between trying to be a reflection vs intentionally not reflecting based on a human-made moral judgement.
What even is the moral editorialization in auto-suggest? It's obvious we don't want conspiracy videos pushed front and center of educational topics, but how on earth do you balance the number of "yes" vs "no"? That's clearly going to be a completely made up number. If you don't have a clear problem to fight, it's probably best to not editorialize just to say you did.
