Did you buy a Kindle Fire because it was the best tablet available, hardware- and software-wise? Or was the price point a concern? Similarly-specced tablets without a leash to a particular company's ecosystem cost considerably more. Where is that deficit going to be made up? Is Amazon just going to give you that extra hundred bucks, extra gigabyte, extra gigahertz, out of gratitude? It owes you no goodwill, it merely owes you a product that is delivered as described. Which it delivers on. Business, not charity. TANSTAAFL, and all that.
Edit: to tie it back to the original topic at hand:
- consumer buys device, uses it in a way which is outside the device's intended and promised scope
- device manufacturer pushes update to device, update reverts user's device back to performing as promised and intended, possibly offering usability and security improvements at the same time
- user throws a fit, cries to heavens, earth and Amazon, saying 'give back to me that which I was never promised'
- other, well-adjusted, impossibly-handsome user (hi, yours truly), says 'actually...'
- intermission, refreshments
