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.
Don’t copy that floppy!
I think the generational shift was mostly that the previous generation just didn’t have or use computers at home, and suddenly they were everywhere. Most households just didn’t have a computer until the late 90s or early 00s. By then, floppies were on their way out, and burning CDs was all the rage.
