Microsoft and Amazon are both less liberal cultures than Google. Microsoft particularly historically has skewed much closer to centrist politically, in its culture, business operations and ideology.

Microsoft is more like old IBM in that regard, which makes sense given how old its cultural foundation is (dating to the 1970s) and its history of working with more conservative old-line enterprise businesses. As are Oracle, Cisco, Intel, etc. All will very happily serve the military industrial complex. You won't find any serious dissent in Redmond.
