I think this is the most pragmatic approach. Quite frankly, these players' intent is irrelevant. It's the results of their actions that matter. However, it is useful to understand the incentives that they respond to, particularly when we have the ability to use those incentives to elicit further good acts in the future.

Many 'activists' seem to think that simply having good intentions and beliefs makes one a 'good' person (and many seem to stop at that point). But as it turns out, a starving person derives no nourishment from your internal happy feelings. I'm glad to see YCombinator understands this very basic fact and is taking action to better society, rather than just sitting around thinking lofty thoughts and feeling good about itself.

"The road to hell is paved with good intentions." Or, in the alternate form: "Hell is full of good meanings, but Heaven is full of good works."
