You might think of Wikileaks as "extreme," but this is an organization that was neither convicted nor even charged with breaking any laws, which Amazon dumped as a customer on very vague TOS grounds following pressure from Sen Joe Lieberman.
This could be an issue for reasons like...
-You make a Web app that Hollywood deems to somehow encourage or abet piracy
-You provide a service used by a customer deemed to be politically controversial
-You facilitate financial transactions deemed to be potential helpful to "terrorists" or the wrong sort of activists (e.g. Wikileaks).
Werner, since you submitted this entry from your personal blog, maybe you could clarify what safeguards Amazon has put in place to prevent a repeat of the Wikileaks situation. Many companies will stand behind a customer barring a court order, but for Amazon this clearly is not the case. How do you decide when to abandon a customer?
