The problem is this isn't well defined. Somewhere maybe in the 1980s greed became good and the responsibilities of corporations shifted from being a fictional person that could benefit society to a thing that was in it for shareholders only. This is a cultural shift borne by MBAs and thinktanks, not something that can be pinned down to a specific incident.
As usual sunlight is the best disinfectant. It needs to be clear who owns what and who did what, and journalists need to go and look at cases where things are not in the interest of the community. There need to be records of whose interests are represented, who owns what, and who knows who.
