We all know, before that comment, Amazon wants you to vote no. The OP was adding to that, in criticism of Amazon, by saying there are detailed six page instructions on how to vote the way they want. But that doesn't tell me what's to be outraged about -- as the first response noted, that is exactly what every other campaign does.
If the OP wasn't claiming Amazon was outrageous beyond the mere fact of asking for no, then why even bring up a six page instruction set?
