I have. As far as I can tell, there was no entity competing with Amazon here. The main other corporate entity involved was running a front-running scheme on real-estate transactions.

Obviously you couldn't be in good faith talking of the company front-running land purchases and reselling the same land a day later for 20% profit as a "competitor" of Amazon.

So, again: who is the competitor you have in mind, and what business do you think they're in?
