I would love to know the real motives. I don't automatically buy the "ensure fairness for the middle class and working people" line. "Love for the people" is always the stated motive of all oligarchs and tyrants. And frankly, these politicians aren't exactly in some adversarial relationship, or at the very least a legal supervisory one, with corporations. That myth died a long time ago. Better to ask: why would corporations allow for something like this? Why would their political allies push for this? Somehow it must be in their interest. Perhaps they're hedging because they sense a real threat and have chosen to concede in some way, or perhaps this actually contributes to furthering some perceived advantageous end.
