Advertising just keeps getting heavier and heavier and heavier. It doesn't have any natural limit, and we haven't found the place for the limit. And I think it's really important, therefore, that some of the revolts that are undergoing right now, you know, whether it's ad blockers or other things, are people trying to set some lines so that we say, you know, this far but no further. And this is where it ends.

Facebook, when it began, like Google, was very resistant to advertising. They knew, like all - Mark Zuckerberg, like all good engineers, knew that advertising makes the product worse. But, you know, over time, they've been forced to increase the advertising load more and more and more. And the way they advertise is they - it's subtle but they know everything, you know, about everybody on the site.

When you decide to like something, I mean, you may feel you're sort of innocently putting out your preferences, but actually you're delivering something of enormous value, which is indicating that, you know, you'd essentially like to be advertised to by this company.

I want to say, however, one thing our media in America has done which didn't happen in other totalitarian states is it has very effectively stood up to Donald Trump who has obvious fascist tendencies and his - who's a temptation like all authoritarian figures to try to crush the media or make it obey him. As that - the media has, in fact, stood up to him and has refused to bow out or cower.

Google - and some of the other sites, YouTube and, you know - Google has an amazing search engine. The map product is incredible. So there's a sort of exchange when you put up with a bunch of ads. Facebook basically gives you access to your friends who, in theory, you had access to already. So sometimes I don't really understand the deal, but I guess it makes it slightly easier. So that's their contribution.

Net neutrality is the principle that the service providers who control or access, who own the pipes, should not favor some content over another. It's, you know, an even playing field for stuff on the Internet, and, you know, I think it's very important to the medium that it have a rough quality among contents. Everyone has their shot.

There is this inherent human instinct that the usual way you control trolling is you force people to use their real identities. So there's less trolling on Facebook, for example.
