Consider:
1. Ebooks go through great length to make the information behave like a physical book.
2. Libraries have to buy as many licenses as they can plan to lend our concurrently
3. Licenses will even expire after a bit, because that's what real book do, they wear of.
So far so good (if your goal is to simulate real books). But now:
1. Wanna give your ebook to a friend? nada
2. Wanna lend your ebook to a friend? nada
3. Wanna use the book after companies decide to disable their license servers? nada
4. Imagine a few hundred years from now. We can still look at old books because they exist and their content is not controlled. That would not be possible.
Of course it is always possible to remove the DRM protection, but that is illegal.
We've been duped.
