I guess laws in my state laws are different. Theft is illegals, as is trespassing on private property.
Didja read the End User License Agreement? that prolonged fine print which few read probably had a “user agrees to allow deletion & refunding of materials found to have been improperly distributed” or some such. Think “repo man”.
Like I said, copyright laws are notoriously biased in the favor of the holder.
Just like most other property rights, but copyright laws deals with things that can’t be physically stolen or even protected (although some try - DRMA). Once they’re out there, they could be fair game.
As such, copyright law is given precedence over a lot of other concepts.
I agree that it seems logical that your Kindle is your property, but copyright law might just give Amazon all the power they need to enforce it.
