I view corporations as non-human intelligences, so while it's totally unethical for a human to manipulate the law to their own ends, it's also something I expect corporations to perceive as acceptable, in as much as that makes sense (they will not shun each other for it) and in much the way we humans generally agree it's wrong to kill but we don't shun people for amputations or appendectomies.

This is why I prefer democratic corporations, rare as they are, to pure capitalist ones — at least the metaphorical appendix has a vote.
