They have, as the joke goes, more money than God and influence all over the world. They are beholden to no one. They have the resources to fight in court against decisions they don’t believe in, and all the lobbying they need to shape established laws.
They choose their actions, and their actions are their own. Every single dollar they donate to the current president but not the previous one is an admission of their allegiance and (lack of) morals.
Having principles and standing for them costs money, and these societal parasites subsist on money and influence. Make no mistake, they will sell their own mother to further their goals, but they don’t have to while they can keep selling everyone else’s.
