I have bought all humble indie bundles so far. I was always paying below average.
I didn't have time to play any of the games though so I have probably not exploited anyone's hard work (yet).

If I'm hitting some paywall while searching for something crucial for me I always go extra mile to find the thing I need (or equivalent) without paying.
I sometimes pay when acquiring software but I don't view it as paying for but rather as voluntarily supporting a cause.
That's the case with Humble Indie Bundle. I think the idea of "pay what you want" is worth the support.
