The point is "Amazon" is just a word used by South Americans to name things in their culture, in the same way that Bezos names his company "Amazon".
The fact that they sold the TLD to the the company is a little sketchy, but the idea that South America has an inherent trademark on anything "Amazon" is ridiculous.
So it should be a common name, like "water" or "air" and that domain should not be on private hands. But if I had to choose between a beautiful river and its surrounding rainforest and a company which forces some of its contractors to pee in bottles I know who I will choose.
