Zuckerberg knows that the power is on Pennsylvania Avenue, not 1st St. Maybe he'll change his mind in a couple of years, but he's going to spend those years doing his best to ensure that he doesn't have to.
Of course he knows where his bread is buttered. And he will cozy up to the new powers too. He has no spine. No moral code. It’s all power and money and meta. Fine. Good for shareholders. Bad for young men everywhere trying to pattern themselves after these barrons of industry.
