The article states that the rules changed in 2011 that allowed Amazon to purchase the domain. Which they attempted to do in 2012. At what point in time would the Amazon region have been able to purchase it? Having a hard time looking up what the rules might have been, but I would think they could have gotten it issued before then, under old rules could they not have? Seems like there wasn't interest in the domain until someone else proposed it, or were they also working on it too?
