Welcome to the comments section of the Daily Mail, knee jerk reactions without actually readin past the 1st paragraph.
The concept is the ability to sell to another person (everyone is saying this is Amazon selling the items, but it will actually be end users via Amazon) and make to sure the original is destroyed.
So for a REAL world analogy, you have a CD (yes physical). and you sell it in on eBay. eBay takes a cut, you sell the original and the original is "deleted" i.e. you no longer own it.
If you rip it / copy it, that's not the same and not what they are trying to do, this is merely to pass an original copy to another person.
Should it be patented, well thats another arguement, but please before the rants, understand the concept.
I'm off to Wired, t's getting more like the Daily Star each day around here.
