Agreed. I outlined such in another thread too:

The cost of the scanners is $$$$, maintenance $. They will want to spend for new toys, and perhaps the manufacturers will claim some sort of "privacy-enhanced" scanner to give to lobby-inspired contractors.
Here is the famous photo of Obama with the CEO of (parent company of) Rapiscan.
This picture makes me think less of Mr. Singh.
No, no, no!!! You don't want this -- what they would do is make the opt-out scan line move really, really slowly. Or, if you get to the scanner and choose to opt out, they might force you to go to the END of the slow opt-out line. I feared they would do this on NOOD but they just turned them off instead.
Thus if you were running late for a critical business meeting you might HAVE to take the nudescope or miss a flight. Not cool. Delaying EVERYBODY for the ridiculous groping is the best strategy to encourage pushback, and hopefully change in policy.
