Some sort of "trickle up" mechanism where if enough people are sufficiently nasty to frontline workers, it'll get back to decision makers who will then change course.
I think that's fantasy and/or rationalization for taking things out on others.
It's the same thing with customers who make a big scene about a missing fries or something. 99% of the time it's not a problem and nobody cares - here's your fries, have a nice day. 1% of the time the person cares less about the fries and more about being hostile about it on principle/for fun/for respect/because they are in a bad mood/whatever, and those are the ones that suck to deal with when you're there but not in charge.
So the premise is "the customer is hostile".
It is a bit off to attack the drones of a corporate, albethey the only available target?

You see, the following headline has more effect on CEO's and decision makers
"McD's sales drop 10% after customers refuse the app and other forms of spying" --Forbes
If it's a silent boycott then you see stupid headlines like
"Are millennials killing McD?"
Remember the entire purpose isn't so that one company doesn't track you with an app, is so every company figures out tracking you with an app is a bad idea.
