DuckDuckGo has ranted for a while about Google's "search bubble", where it shows each user pages likely to confirm their biases. This twists that old habit, so now everyone will be presented with pages likely to confirm Google's biases. Disagree with the Google groupthink? Your page is filled with lies, and Google will do its best to hide it.
Your own good judgment is the only worthwhile filter, and you don't get or maintain that by seeing only pages that all say the same thing. You don't really understand any subject until you can argue both sides in detail, and see why those with the out-of-favor view believe what they do!
I don't expect it will take very many years before Google picks sides on politically contentious issues in their ranking. Is abortion murder? Don't worry, Google will decide for you! Is recycling actually helping the environment? Don't worry, Google will decide for you! Are the current Net Neutrality changes actually good for the consumer, or only for internet giants? Don't worry, Google knows where the facts are!
Whatever you do, don't spend the time to study issues in depth for yourself, no, don't rise above your station. Repeat what you've been told, and everyone will say how smart you are - well, at least everyone who shows up in a Google search.
