Google became popular because it ranked sites based on popularity. Once they got almost everyone onboard, they changed midstream to now push their values on US.

Google Moving to Shut Down Alternative Media by Ranking Sites on “Facts” Rather than Popularity

Wants To Cross Check Websites Against Debunking Sites Such As Snopes.com

Search Engine giant Google, the major driver of traffic to the majority of media portals is moving to change the way it ranks websites, declaring that it intends to use known partisan debunking outlets to determine the “truthfulness” of content.
Currently, Google rankings are determined by the number of incoming links to a web page, meaning that if a story becomes popular it can be driven to the top of search results, and by viewed by millions of people.
However, this is a little too democratic for the liking of some, who only like to get their “facts” from pre-approved sources.
The proposed solution, according to a Google funded research team is to compute a“Knowledge-Based Trust score” for every web page, based on Google’s own “Knowledge Vault”, an automated database that determines “facts the web unanimously agrees on,” according to the New Scientist.
“A source that has few false facts is considered to be trustworthy,” says the research team.
In short, any web pages that provide information that contradicts or questions Google’s own established “truth”, will be bumped down the rankings.
In addition, some of those working on “truthfulness” ranking technology have expressed a desire to verify or rebut web pages by cross-referencing them to other sources, such as Snopes, PolitiFact and FactCheck.org. These websites exist and profit directly from debunking anything and everything. What’s more, they have been previously exposed as highly partisan.
