So you already have freedom of speech. And the Government is not allowed to restrict it with any new law. The US Constitution was not made to give you rights, but to restrict the Government from taking them (although it seems lately they don't seem to even acknowledge the Constitution exists, and people should be more outraged about that, because if the trend continues, it's not a matter of "if" it will hurt you, but "when").
Wozniak is wrong on that one. I think he got a little confused thinking about net neutrality. But net neutrality plays into this very well too. We already have the freedom of net neutrality, because that's how the Internet has always worked.
Net neutrality just ensures that the companies can't restrict it or abuse it in any way. This is exactly what Al Franken said in the interview with TheVerge, too:

I don't think there's anything like this in the US Constitution, but net neutrality is trying to be just another bill of rights basically, saying no one can restrict or control how you're using the Internet. It's just that it's a law, not an amendment to the Constitution (though maybe it should be).
