Looking at his specific words, it appears he is referring only to cyber attacks, hacking, fraud, and internet piracy, not regulating speech of any kind.
Of course not.
It would be supra-national, UN organizations coming to just determination of what constitutes hate speech, defamation...or even release of Court Proceedings as you have in Canada and Germany today.
Since we have turned over the control knobs of the world-wide internet to the world, we are not likely to have much official say in what does and does not constitute restricted or forbidden speech.
The USA has THE most (l)iberal and protected speech laws AND practice in the world.
And we just turned over the Internet to people who don't care.
And, they could turn either you or I off anytime they damn well please.
How would an international tribunal handle such?
