In my righteous indignation, I forgot to deliver the point. So here it is:
Even if Amazon gives up their patent claim, it will not be the end.
Big corporations and newly big Ecommerce corporations has this DNA that tells them to profit/expand at all cost. Sometimes we need to stand by grassroot communities that stand in their path of relentless expansion, be they open source communities, local bookstores, or forums like this one.
A community fosters surprising innovations, gives people a shared identity, and in the case of physical book stores, gives back to community in taxes. A community is a common home which needs care and unending vigilance.
Next time when you need a book, resist the urge to point and click to Amazon, and point down the local bookstore instead.
