I'm wearing a Fitbit now (not for long, just ordered a Garmin watch I'm excited!), but I'm pretty sure if I was forced to wear one, my Fitbit would be the victim of a "totally unintentional" prolonged bath. Having said that, I choose to share my step count with my health insurance company, and by making 0 changes to my lifestyle I've gotten a 10% discount on insurance premiums (you're welcome employer covering them), and points that I've used to get two $25 Amazon gift cards, 1 $20 iTunes gift card, and 1 $12 movie pass. If it benefits me, I'll do it, but I'd resent being forced to and I'd probably do less than ethical things to show my displeasure.
