But it does demolish any legal logic used to justify this board policy.
The point of the policy, I presume, is to immunize Jim from lawsuits lodged by copyright holders. But if the world's largest online retailer is selling the product, arguing that linking to such products will amount to likely lawsuits for Jim makes no sense. The point of a lawsuit is to obtain relief from harm; if nobody is bothering to sue Amazon, which is causing about 1,000,000x the harm Jim is in such a case...then why does Jim have anything to fear? It's asinine.
This seems to be the "relax and enjoy it" answer.
