Sure, you can find extremists on both sides: the "nationalize Facebook" people, and the "nothing on the internet should ever be regulated" folks. Not having read the book under review ("Surveillance Capitalism"), I can't say whether the author is all the way over in the "nationalize" camp.
But currently, we need more regulation, not less, on internet companies whose business model is based on selling your attention to persuaders at a time when you are most vulnerable to persuasion. So although I don't favor nationalization, and I don't begrudge Zuckerberg his vast wealth, I want to see things move in the direction of more regulation, not less.
There is a slippery slope no matter where you stand, but yet, you have to stand somewhere.
