I agree this engineer will probably lose the case because Apple has better lawyers, but I believe your underlying argument to be incorrect. If your manager asks you to violate company policy, then the correct response is to not violate company policy and instead contact HR/legal. Otherwise, saying “my manager made me do it” will not save you if heads start to roll. This applies to both policies that are strictly internal as well as policies that are due to an underlying law. When it comes down to it, neither you nor your manager actually interpret laws or internal policies.
