As long as you've raised the issue to your manager, they're responsible for it. They've given a reason, and this includes a business case for their justification. You're neither responsible nor accountable for their decisions (which you've informed them of). You have raised your concern. A bigger question for me, is this a systematic thing in your company? Or just your manager? Or ripping of other things is OK too? If so, at some point there will be negative repercussion, and at that point no order of internal memos will separate you from the brand you worked with.
