Cutting off access to information in such a barbaric, offhanded way is the logical conclusion of the monopoly structure that enabled Amazon to do this without repercussion. A triple monopoly in this case Amazon/Kindle/ E ink.

This will disproportionately impact those who do not live in the US/UK and rely on their subscription as the only reasonable means of timely access.

I urge you to write to write to jeff@amazon.com to voice your displeasure.
