Personally, the return policy never bothered me. It never even occurred to me that it might bother others. Here is my response to the article:
Self-published authors are often looked down upon as lazy people who are taking the easy way out and cheating their readers with a sub par product. So I like that people have seven days to return the book at Amazon. That means that anyone that kept it probably felt it was worth what I charged for it.
I'd say about 5% of my books get returned. Considering I give out thousands for free, that number is nominal. They aren't "gaming the system" when each time I do a promotion I give away WAY WAAAAAY more than anyone could get from reading and returning.
So, I like the return policy, I think it keeps us as sellers honest. I'm not to worried about dishonest buyers because if I like a work, then I'm going to want to support the person that produced the work so they have the motivation to produce more. I'd like to think the majority of readers have a similar attitude. And until I see like a 50% return on sales I have no reason to believe otherwise.
Plus, people would be able to borrow it for free if from a library if it wasn't a e-book, so think of returns like them borrowing it from the library (which is more affirming than they hated it so much they wanted their money back, lol).
And one day is far too short. I rarely buy a single book. I buy 5-10 books at a time. Which means only one book gets read immediately. One day isn't even enough time to make sure the book doesn't have formatting issues let alone if you liked it or not.
