They probably want the money and reputation that Amazon gives them. They have that to lose. What you're saying could be applied to anything people do for their own interest. Taken to the extreme - Afraid of starving? Should have just died instead, then you wouldn't need to depend on food.

I think some aversion to certain social situations is part of the core human condition, not to be blamed on any particular socioeconomic system.

Corporations have a wonderful and easy way of measuring how much your time is worth.

Your salary.

If it costs less (salary * time) for you to decipher the cryptic email than it would cost (their salary * their time) for your bosses bosses ... boss to write a non-cryptic email then you deal with it.

This isn't kindergarten and it's not about your feelings.

So true. In communism, nobody would have power over you and you would never have to fear your superior. History has shown this to be true.
