What this court decision establishes is that you cannot treat the digital books the same way you can treat physical books. For example, you can re-sell or lend a physical book under "first-sale doctrine" but you cannot do the same with a digital book. So "they the people" have less rights now.
The upside that you can lend a book without visiting a library; if you live in a remote area you don't need to travel; if you like reading at night you can do it; if you are a foreigner or illegal migrant, you can lend a book too.
So digital library, lending books over Internet is much better than a physical library.
Exactly. If you're going to defy publishers it is better to go all the way and offer ebooks actually for free instead of doing the CDL's stupid DRM scheme.
