I think you fundamentally misunderstand what Amazon is removing. From your linked article:
Once this feature goes away, you’ll still be able to manually copy ebook files and other documents to Kindles over USB using Amazon’s apps or third-party solutions like Calibre. You just won’t be able to download copies of your purchased books to a computer.
The only thing Amazon is removing is the ability to save books that you purchased from them. No more personal backups of legally purchased material, but piracy is still fair game.
