Despite it being off topic, can we define why those claims are questionable? Is their data proving those claims wrong? Because with all the Google political controversies over the past few years, and given the political donation history of Google employees, it’s highly plausible that search results are manipulated to favor certain politics over others.
If the “questionable claims” have been disproven or are inaccurate, then it would seem that you’d provide some proof. Essentially, it you are to claim the search engine was not biased towards Clinton, certainly there would be some proof of that? It’s more reasonable to suspect Google manipulating search engines than not, given the political environment at Google.
The real “questionable claim” is that Google is neutral in any way — which is kind of the entire premise of the article. If Google were completely neutral, then why would their monopoly on search need to be broken?
