Very rational. I agree that the Amazon model is not broken, its just different (I did not mean to suggest it was broken, though I can see that being implied from my statements). I also agree that it is OK for the developer to publicize (critically) that there was an alternative/non-public agreement to become the app of the day which varies from the publicized terms. At the end of the day, you are both "right". There are types of apps that this can work well for (which I think you do a good job arguing for) and there are pitfalls to the system which Amazon tries to not make public (which I'm thankful to the author for having written about).
