So why would Nike want to limit the amount of money it can make by excluding millions of Android users? Simple. Apple came to see Nike and said "hey, we are about to release the iWatch, which is going to eat your fuel band alive. Why don't we partner up so you can continue to make money and we can benefit from your experience in the arena. The new Apple iWatch with Nike built in. Of course if you want to do this partnership, we will need you to make a public statement about not supporting Android."
Not like Apple had to travel far to go see Nike.... The article failed to mention Tim Cook sits on Nike's board of directors.
He's already starting to get dinged for conflict of interest with him sitting on Nike's board while Apple is making its own version of wearable gear.
Wonder if he'll have the class to resign from Nike's board =p
