Is more appropriate here.
Finding a $20 on the street falls within the realm of reason, and is not likely a scam. Finding a suitcase full of cash however, and picking it up probably has strings attached.
It's probably clear to everyone that the cost in the end is going to be bigger. If you watch Raed667's video, the municipalities involved are quite upfront about it and not really trying to scam anyone.
But basically you can see that as a subside or a promotion. The fact that there is going to be other costs associated doesn't means the market ruled it as a bad deal as bobwernstein claimed
