Man, this turned into an argument fast. @_@
Anyway, I honestly don't care whether people buy these games or not, as long as they don't pirate them. It's a good cause, and it supports indie developers, who supply the industry with the creativity it so desires. In all honesty, while I support the charitable part of this purchase, my main motivation would be to suport the devs. I really want to see creative work rewarded, because I really think the industry needs to see it.
As far as piracy of the bundle, I think Wil Wheaton says it best.
