My right wing friend argues that Google straight up manipulated search results to harm Trump and I don't have any evidence to argue against him.
I wouldn't be surprised if there's an anti-alt right bias (which frankly I don't feel so bad about because many of those folks are toxic).
Also, to be pedantic that's a misapplication of Occam's razor. The simplest explanation to explain nature is likely true. Nature likes simple laws. People and organizations, however, can be endlessly complex.
