Complying with the law is just another way of protecting your money. I have no doubt if they would break laws if they judged it better for the bottom line --- in fact I have little doubt they're already doing so. On the flip side, if there were ruinous penalties for their anticompetitive behaviors (i.e., in the tens or hundreds of billions of dollars) they might change course.

Certainly voters need to have their say, but often their message is muffled by the layers of political and administrative material it passes through.
