Who ever thought that a closed device that allows only apps sold by a device maker is a good idea in the first place? The whole scheme looks so ridiculous. In a sane world such practice would have been found illegal long time ago. If some people accept this control that is their choice but the device makers should be obliged to give a jailbreak code to anyone who asks for it.
Amazon is equally guilty of the dictator disease. Kindle can't read epub files and their updates are actively trying to "fix" the jailbreak for those who have installed FBreader. If there is a hell then there is a special place reserved in it for those bastards.
