You can ask this about a lot of foods. How do you know your baby formula isn't just crushed white building material mixed with water? (This happened btw, see melamine baby formula). In the end big conspiracies like this leak out since there's a lot of employees in the supply chain and trust in the brand is broken. The Chinese go out of their way to buy Australian and New Zealand branded baby formula to this day because trust in their own local brands was destroyed. So this is unlikely. Possible and similar short sighted things have occurred in management before (see Boeing) but it would be ridiculously poor management to let something like this happen.
