The review manipulation offer was boxed up in the shrinkwrapped package so from my POV that made it part of the product. If the seller is altering the product then IMO its fair game to review. If a seller removed the batteries or put a sticker on the product I'd consider that an alteration to be part of the product itself... as opposed to when reviews complain about stuff like the seller's shipping speed which is orthogonal to what's in the box being shipped.
