I'm guessing that when someone purchases a kindle fire somewhere along the line they agree to a user's license, the terms of which are violated by rooting the device. I don't care if people root there devices or not, but I cringe at how routinely people agree to something that they know up front is a lie on their part. I'm sure some people will respond with the following:
Liar: I bought the device so it's my right to root it.
Me: Does your neighbor have the right to open a garbage dump in his front lawn and ruin your property value. It is his property.
Liar: Hey, my rooting the device doesn't hurt anyone else.
Me: Yes it does. It helps destroy the business model that makes the initial cost of ownership lower for everyone else.
Liar: Well I'm just one person, I'm not going to bring the business model to it's knees!
Me: Oh, sorry, Mr. Liar. I forgot that just because it's you doing it and not everyone else, then the normal rules don't apply. Do you also think it is okay to steal from a charity because if it is only you doing it, then the amount of money will be so slight as to not be noticeable?
Self Centered Liar: Well that is different. Stealing from charities is taking something that is not yours to begin with. The kindle is mine, I bought it.
Me: Yes, but your defense to weakening the business model was based on the fact that not everyone does it, just a few people. I'm just pointing out that this argument cannot be used to absolve you of moral bankruptcy.
Liar: Get off your high-horse you piece of crap.
Me: QED
