It is if they want to bet on the value of bitcoin. Why use some hardware for 40-60 days to mine some coin which may or may not be worth $1500 when you could sell immediately for that amount? Sure you can mine for longer, but I'd bet they have more stable returns by investing profit from sales back into the business for fast/cheaper manufacturing, expanding their area of operations, etc.
