Sorry, but we face this every single day, with every single industrial food that include extra ingredients (e.g. preservatives) wrt to old granny's classic recipe and we don't call it "consumer deceit". It would be a fraud if the label on the product you buy omitted some ingredients, but it's not the case here: Microsoft doesn't claim its binaries are the result of a vanilla make on their source!
