Most philosophers start from a premise they want to be true and work it out until they have a proof, (sometimes) claim they did it the other way around and make use of one or more subjective statements in their proof. The subjective statements are usually true to some people and false to others and therefore arguments about a proof are almost always about one statement and evidence to support or refute its viability. I was a CS major and a minor in philosophy. I think philosophy is a good major and a good minor. On the major side, if you're talented and ambitious you could have a degree in performing arts and succeed far better than a lazy or incompetent person with a CS degree. On the minor side, I understand your argument that mathematics is the "real" philosophy as it is more directly applicable to pure CS. However, math has nothing to do with human motivation, ethics or other such philosophical concerns which are very, very applicable to working for a company that happens to be doing CS ;-) Plus, metaphysics is pretty damn fun.
