It's a fair question, and I personally don't see a good way around the legalities of this. However, the moral questions are quite obvious, and it seems obvious to me that there would be consumer watchdog groups (like Consumer Reports) that would keep us abreast of these antics. Even if the law can't pierce the corporation, crowdsourcing and reputation certainly can.
