As to the rest of your "point"(?), corporations-no matter the leanings of the individuals who may be their public face, ala Bill Gates, tend to lean with the conservative, free market, limited regulation approach to politics-as the corporate entity stands the most to gain from this.
I've never though of Bill Gates as being or leaning conservative. Salon did an interesting article on Gates several years ago which discussed his political leanings: http://www.salon.com/21st/feature/1998/01/cov_29feature.html
Since this article Gates has gotten more involved in causes which could be portrayed as being to the left, including pushing for more taxes and more regulation, especially when it comes to Climate Change (formerly known as Global Warming, but soon to be called Biodiversitee).
