Sorry but then your company then goes under after a large percentage of your customer base returns your products after they stop working.
You can spec the designs ALL you want to use authentic chips, but when your company's accounting department sees they can save a few cents to a buck per device by using the less than authentic chip. You're pretty much sunk.
Even if the accounting department agrees with you, and you get the company you work for to have boots on the ground in your manufacturing plants to make sure you use authentic parts. Even then you can't tell the chip is authentic until you destructively open it up and look at the silicon.
To put it bluntly as long as they exist the entire apparatus of the corporate machine is geared to use them because they provide the exact same function as the authentic chips at a lower price.
