No the op's point is that to comply with the licence you need to provide the source to customers that ask for it. She's trying to save you some potential trouble.
If his customer asks, he doesn't need to do shit if his customer doesn't ask. My recommendation would be do what the likes of Toshiba do for their TVs include in the product an offer with an email address on some hidden copyright page.
That offer is in fact mandatory, if one doesn't want to include the source.
Ah, yes that's all included in documentation sent with the device. I was confused with the question.
