I'm not a huge fan of corporate giving, but the counter-argument is that when you have one big donor instead of a lot of little ones, and objectionable decisions by the company can be boycotted. For example, Coors used to give to a lot of right-wing organizations and also had a lot of anti-gay hiring practices. Gay organizations targetted them and eventually they not only stopped donating to those orgs, but they changed all their corporate policies.
