Barry Sonnenfeld is a dumb shit. If anything the opposite of what he is saying is true, the wealth of information that is available to pretty much anyone on the internet makes it almost impossible to hide anything from the public eye, and people can become more engaged in the public policies and how they want their country run.
Sure the internet has its bad "addictive" sides, but thats got nothing to do with democracy, or the lack of privacy.
Its quite easy to keep your privacy on the net, unless youre a dumb shit like Sonnenfeld (who probably got scammed into giving his credit card info on some fake gay porn site)
I have a nifty blue line!
