This is great confirmation of stuff we already knew in pieces or suspected, sort of like wikileaks. It's good to have as ammo when leftist NPCs repeat their "There's no search bias. You're just being paranoid." and "Nobody is censoring conservatives, you all just break the rules more." scripts.

Though my favorite mantra from the more techy types is that Google's algorithms are all black box neural networks and even they don't know how they work.
