It depends on the scope I think. There's obviously nothing stopping anyone from running other browsers, blocking tracking as best they can, anonymizing as much as possible, or hell even starting their own networks to avoid it all together. The technology is still there, still open and free. But the net now contains the general populace, and as such significant power has been amassed by controlling it. I don't believe the internet as we know it is in the hands of the netizens anymore, and I have to doubt that the majority of the netizens would even care. Google and Amazon have both showed continued behavior showing that they'll eat, buy or smother anything that comes a little too close to them, why should we expect that it would be any different if we tried to kick their behaviors off the network?
