Suffice to say, since Amazon has not publicly commented, TLS is just pure speculation, but I think this is the mostly likely explanation. This is why they Amazon can’t simply issue a firmware update to fix the issue.

This is partly due to them only supporting TLS 1.0 and 1.1 and due to older hardware, won’t have the necessary permissions to make store purchases. I believe this likely due to a TLS issue, since the oldest Kindle models have an older version and likely can’t be upgraded. Amazon has not disclosed the reason why these particular models are going to lose store access. This is the first time that Amazon has ever totally cut off store access on a series of Kindle e-readers. Existing books that are on these models will still be accessible. The only way you can have books delivered to these devices to buy them from your local Amazon website and have them delivered to the Kindle. The company has stated that the Kindle (2nd Gen) International, Kindle DX International, Kindle Keyboard, Kindle (4th Gen), and Kindle (5th Gen) will no longer be able to browse, buy, or borrow books directly from these Kindle e-readers. Amazon has just sent an email to a number of Kindle users who have older e-readers on their account.
