Sure, but that obviously isn't what people were talking about with respect to developers giving refunds. I provided that feature to developers in Cydia and gave refunds directly to users and it was still appreciated by all to have that feature.

Regardless, to address your (off-topic) addition: do you actually request refunds from Apple often enough to be willing to pay 10% more for the privilege? You'd have to be asking for refunds for 1 out of every 10 products you buy for that to make sense...
