Although you're absolutely right about Apple and any large company using their leverage on suppliers. Those are EXISTING suppliers with prior business arrangements/relationship with Apple. So they CAN be leveraged because supplier can see their sales orders fall when Apple stops buying from them.
HOWEVER, this was completely NOT the case with Apple & GTA arrangement. This was a new partnership and GTA did NOT have prior arrangements or relations with Apple. Because of that, GTA would not see a reduction in sales orders or revenue from Apple. Therefore, there wasn't any strongarming to be done in the first place.
GTA was not strong armed!
I completely agree with you, actually. I'm just saying that I understand why people would look at Apple's actions and classify them as aggressive. At the end of the day, GTA was done in by their own decisions. Sad for the rank and file employees, of course.
