Wow, that is such a clear analysis that someone should transcribe it. Here's the main part of what Naval says:
"If Google, Facebook, and Twitter had been smart about this, they would not have picked sides. They would have said "We're publishers. Whatever goes through our pipes goes through our pipes. If it's illegal, we'll take it down. Give us a court order. Otherwise we don't touch it." It's like the phone company. If I call you up and I say something horrible to you on the phone, the phone company doesn't get in trouble. But the moment they started taking stuff down that wasn't illegal because somebody screamed, they basically lost their right to be viewed as a carrier. And now all of a sudden they've taken on a liability. They're sliding down this slippery slope into ruin, where the left wants them to take down the right, the right wants them to take down the left, and now they have no more friends, they have no allies. Traditionally the libertarian-leaning Republicans and Democrats would have stood up in principle for the common carriers, but now they won't. So my guess is, as soon as Congress (this day is coming if not already here...)... the day is coming when the politicians realize that these social media platforms are picking the next president, the next congressman. They're literally picking, and they have the power to pick, so they will be controlled by the government."
