What a cop-out. Everyone should want the company to succeed. So why not say "Hey, boss, this KPI won't work, here's what might happen..." instead of literally working less than needed to prove some point? It's dishonest.
The company has no interest in my success, why should I care if the company succeeds? It has no effect on me if it does.
"That's my only real motivation is not to be hassled, that and the fear of losing my job. But you know, Bob, that will only make someone work just hard enough not to get fired"

Put yourself in the same boat: if you had a team to manage, with the freedom to give them incentives, and they didn't have the effect you expected, you should be able to notice it and try something else.
That's great if the team is helpful and tells you exactly what's wrong, but you should also be able to evaluate how it's going and react accordingly, otherwise you're just asleep at the wheel.
