I don't understand why people put stuff out under the Berkley License and then complain about a lack of credit or a lack of reimbursement (in support or money) for the use of their code. Isn't that the actual point of the license?
Intel telling him about it at some point would have been polite.
Intel has paid one billion to AMD to settle a law suit. I wouldn't expect a company which doesn't refrain from illegal activities to be polite.
