Seeing capitalism as amoral discounts the fact that capitalism a system used by humans. It's humans who are being amoral to attempt to enforce obviously bad patents. A rational and moral human shouldn't enforce (or consider there to be any value in) a patent that is obviously overly broad -- any more than a rational and moral human shouldn't attempt to steal someone's house because of an error made by the government in recording the deed.

I vehemently disagree that you can "blame" the patents. It's humans all the way down.

I agree with you on the STRATEGY -- the best way to fix the problems is to change the rules. But I will continue to call people amoral/unethical and lob lots of hate in their direction when their behavior justifies it, regardless of whether they are technically breaking the law. A parasite is a parasite.
