Several organizations have boycotted Amazon for that:
The rest of the engineering community by and large doesn't understand what software folks are ranting about. People don't accidentally infringe on the OFDM patent, people don't accidentally come up with the same chemical formula for a drug. To them, people who oppose patents are in the same bucket as Chinese companies who rip off American technology--they want to copy other peoples' work for profit.
This is not to say that patent reform in the area of software isn't beneficial or desirable. But the attitude that anybody who opposes it won't listen to reason dramatically overstates the universality of the arguments and the consensus around the position.
But the message doesn't ring true if the messenger's actions contradict the message. If I come to you and yell "the building is burning down!!!" and then sit quietly at my desk to continue coding, do you seriously tell me that my actions do not affect how you interpret my message? Bezos could announce he is relinquishing and freely licensing the one-click patent today if he really believes patents hinder innovation and that is bad for society. Then his message would be consistent with his actions. If you don't like this as logic, consider it as an unavoidable fact of human psychology.
