Let us imagine there is one chocolate product.

The producer gives you two options to aquire that chocolate.

First option is a pile of ingredients, a plain plastic wrapper and a recipe. You are obviously required to make the chocolate yourself, but what you get is the original chocolate as advocated by the company.

Second option is a finished product that has a pretty decorated package and tastes a bit different than original chocolate. You can't quite put your finger on why, but at least you don't have to make it yourself!

Maybe "fraud" is a bit too strong word. We could go with "consumer deceit" instead.

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!
