Well, maybe it is merely a politically pragmatic and stealth approach to securing the legal sanction of NSA spying legitimisation whilst avoiding the risk of any more blowback from the Snowden/NSA revelations.
I mean, it could make sense to use CISPA (or some SOPA**/CISPA** permutation/derivative) to legislate implicit sanction for indirect NSA access, and as a lever to gain agreement from senators who might otherwise be reluctant to publicly approve any new, direct access NSA spying legislation.
Those senators might need to save face that way.
From what I have read it's all pretty much a foregone conclusion. It's gone too far, and there's too much at stake, commercially and politically, for government to allow retraction on this matter.
From the evidence - i.e., what we have seen so far - you are arguably up against the usual remorseless totalitarianism/fascism, and if you don't like it then you will have to lump it. Chances of change and survival AS-IS are probably equivalent to the proverbial chances of an ice cube in Hell.
You will get that legislation passed, one way or another, regardless. So, "forgetaboutit" - quote from Donnie Brasco, which context was also American gangsterism.
