How copyright law gives Amazon too much power over the book industry
And while the law was passed at the behest of content creators, it also gave a lot of power to platform owners. If you buy a movie on iTunes, you’re effectively forced to continue buying Apple devices if you want to keep watching the movie. Tools to transfer copy-protected movies you’ve purchased from iTunes onto another platform exist, but they’re illegal and, accordingly, not very user-friendly.
Amazon has taken advantage of the DMCA too. Kindle books come copy-protected so that only Amazon-approved software can read it without breaking the law. Of course, software to convert it to other formats exists, but it’s illegal and accordingly isn’t very convenient or user-friendly.
