I think there's some truth to what you're saying, but it's overly simplistic. Rights and technology are orthogonal. The record is hardly a progression of the powerful using new technologies to trample our rights; it's hardly the opposite either. Rights are demanded, and taken, by threat of loss of legitimacy for the powerful who refuse us those rights; they're lost when that threat is unsupportable. It may be that technology and disparity of power have advanced to the point that that threat is empty now, in which case your point is spot on. But I don't think we've reached that point. Yet.
I will say that the all is lost attitude isn't helping though.
