Devolving the internet & its services isn't the answer. You'd also have to just stop using cellphones too. There is no hiding from a corrupt government. You can't expect the general population to do all this stuff you're talking about. You have to fix the government. Focus on corruption-in-USgov and NSA, they are the enemy. Anything else is a distraction because it's not reasonable to say "Don't make a useful service for millions of non-technical people". Somebody, something, will always be popular and become a major hub of communication. To prevent that, is to prevent the evolution of not only the internet... but even society in general. And you'd be doing all that to avoid a corrupt-government, which you will fail at because you cannot avoid a corrupt-government. Anyone who thinks they have is wrong; it's just that USgov/NSA isn't interested enough in them yet.
The only exception is Snowden, and we all see the sacrifice he had to make to do it. If we all did that then... well... there is no America anymore. If that's what you're advocating, then you're asking for a nationwide revolution. Which is fine, btw. I'm supportive[1] of that. I'm just saying that avoiding a couple of social sites doesn't put you out of reach of the NSA. You'd have to get a significant amount of US citizens to go completely off the grid and live like hermits... or Snowdens. If that happened, I will happily call that a revolution and celebrate.
