The Department of Justice has filed a revised punishment proposal for Apple, claiming the the iPhone maker instigated the in-app purchase rule to “retaliate against Amazon,” according to GigaOm.

As evidence in its new punishment proposal, the DoJ cites an email from Steve Jobs to Phil Schiller and Eddy Cue. The message references an Amazon Kindle commercial and contains a suggestion from Steve Jobs that Apple force book, magazine, and newspaper publishers to use the company’s “far superior payment system.”

Shortly after Jobs’ email, ebook retailers like Amazon were forced to remove links from their apps that let customers buy ebooks from external sources.

As a result of the new evidence, the DoJ is now suggesting that Apple should allow ebook retailers to offer hyperlinks to products outside of the app for a period of two-years, with no costs attached.
