Google’s search algorithms are constantly changing. Gaming the system is a big industry. Now, Google is possibly going to rank sites partly on their veracity; i.e. do they back up their claims. Various deniers are claiming censorship but: 1) Google isn’t the government, 2) those of us outside Google can only really guess at the algorithm, and 3) veracity has always been implicit in the rankings because people tend to link to believable sites and Google is now enhancing that characteristic by checking against an internal Knowledge Base. Debates will rage; and that’s okay.
