Maybe not everyone, but certainly a non-zero number of people. As I read this I started feeling bad for the daily free apps I've picked up from Amazon thinking the developers were getting paid. At least now that I know I can go actually put money in their pockets. Hopefully others feel the same way.

I had no idea 20% was expected to be paid to the dev and I've downloaded several from the Amazon App Store. It sounds like this dev made an uneducated choice to be featured even after knowing they would receive zero %.
