Uh. No. I just think that files you distribute should have an explicit statement regarding the rights the submitter intended to grant. I don't expect you to put time or effort into making it build or verifying that the licensing is correct or fixing bugs - there's no reason at all for you to do that for sections of code that you have no interest in, and it would be unreasonable for people to demand that of you. If IBM's intent was for the code to be available under a liberal license, just explicitly say so rather than referring to a document that isn't available to the public.
