I came here to say the same thing. I've been on multiple program committees for multiple conferences and it would be laughable to claim sponsors have any influence over what gets published at a conference. Sponsors have much more direct (and visible) influence over, you know, sponsorship of the research itself. But even there, corporate sponsorship is only one slice (and a relatively small one) of overall CS funding. There are plenty of government or independent sponsors who would be happy to fund research that is contrary to big corporate interests.
