Under Section 1201 of the Digital Millennium Copyright Act, it's a felony punishable with a 5-year sentence and a $500k fine to supply you with a tool to remove an audiobook from Audible and play it on a rival app. That applies *even if the person who gives you the tool is the creator of the book!*
You read that right: if I make an audiobook and then give you the tools to move it out of Amazon's walled garden, I could go to prison for five years!
