First off...they DON'T scan every passenger.
I just flew twice last week and didn't have to do anything more than take my shoes off and walk through the medal detector. And if they did send me to the scanner I would have happily gone
If they needed to do anything further that would be okay, too, but they are not legally allowed to touch my appliance.
There wasn't anything different with this TSA experience...it's identical to all the other times I've flown in the last few years
