The facts are slightly different than reported
Apple hasn't changed anything. Kindle readers won't break. When you buy a book through the kindle reader, you're dropped out the app and into a browser. What Sony was doing was allowing you to purchase directly through the app. That's the key difference. By the terms of service agreement that Sony willing entered into, they are obliged to follow the rules that haven't changed.
