It seems like most of the private companies who act in the public's interest are newer ones that are either run by a founder, or still influenced by the original founders ideas from not long ago. Does anybody know of any good counter-examples off hand? A lot of older/larger corporation have pretty bad reputations

(I guess I mean as core business practices, not just "we had a good quarter and can hire some extra interns to give them a start in their careers / donate to that art exhibit")
