People are free to pay what they want for this. That is the point. And if they publicly and willingly admit to paying a penny, other people are free to call them out on it. That is also the point, especially since if we want to see more "pay what you will" options in the future (and I for one do), we need publishers to see that they are financially viable.
Also, no single person on this site is going to win a cheapness war. There are people here who routinely go to great lengths to save a few pennies or to make a dollar in profit. So the whole "in for a penny" thing is expected and not that interesting. If anything, this bundle is a good chance to donate reasonably to a relatively good video game cause and brag about being un-cheap, this being an indie endeavor, and it being the holiday season.
