You cannot stop technology and the spying with technology has been going on one way or another since WWll.
Yes, it has evolved way beyond Orwellian predictions and has escalated during the Bush administration but the Clintons were notorious in the use of this kind of technology. Now with Obama, spying on citizens is totally out of control. You need to look no farther than J. Edgar Hoover to see government abuses of the past.
A lot of this spying was done by intelligence agencies via private sector assets to work around the ‘Posse Comitatus Act’ but the Obama administration and the DOJ under Holder could care less about what the public thinks on using this type of technology to spy on US citizens on US soil.
Not too much you can do about this monster except watch it grow.
