So distinguish between, you're seeing this content because a company paid us to show it to users like you, and because users like you watch similar things. what if someone pays to have similar users be shown things that give a certain impression? the advertiser didn't create the content or even choose what content, is it an ad?

how would you enforce that? without open sourcing it you'd have no way of knowing why a thing was recommended. giving access only to the government is not possible.
