Because you need Amazon more than they need you. If you leave, okay, there's still millions of other self-published authors. No skin off their teeth.
This is the company that forced their employees to work during a tornado and it got them killed. They don't care about what you want or how you feel about the price points, because what're you going to do about it?
So your perception of life in tornado alley is that during the 5 months that there are conditions ripe for tornadoes, two days out of every week, all other employers but Amazon send everyone home (despite that home is probably less well-built than businesses are and that putting them into a car could be a death sentence?) That schools just shut and give up their federal funding for being shuttered so many days? That all businesses shutter their doors two days per week while storms roll through? That's not what happens.
You hear the warnings, you move to shelters. There were shelters in that building and a policy and training. That's all an employer should or can do.
Your assumption is as illogical as thinking every business in California sends people home every day because there might be an earthquake that day. Or maybe you're confusing hurricanes (warning of a few days) with tornados? (which spin out of clouds in mere seconds and seldom stay on the ground as long as an hour.)
Sometimes, there are acts of God, and people die in natural disasters. Amazon may be powerful, but they aren't that powerful. They didn't create the weather, or target their own building (which cost them a lot of money to rebuild) or tell their employees not to use the shelters within the building.
In Tornado Alley, people come to feel casual about tornado warnings because they come so often. Sometimes, they don't go into the shelter. A number walk outside to try and get video of one or go about their jobs. Mostly, they continue to shop at the grocery store or watch the TV.
You want to yell at someone about tornado safety, try the Oklahoma state legislature, which does not require elementary schools have basements or tornado shelters. That's awful. Amazon was no more at fault than a Chevy dealership that was hit by a tornado, or the Joplin hospital hit some years ago. Where are the people screaming about how evil that hospital was for being hit? It would make as much sense.
I love Amazon. It gave me a writing career and makes it possible for me to find and buy rare items that no way could a local store stock. People who hate them shouldn't buy from them or let their books be sold there.
The OP is getting the royalty for the price she set. So Amazon is doing OP a favor, not hurting the writer, by trying to move more of those books.
