Even if you’re uninterested in GT Advanced Technologies, there are a number of details about how much power Apple exercises over its suppliers.
Squiller says that Apple did not ever really enter into negotiations, warning that GTAT’s managers should “not waste their time” negotiating because Apple does not negotiate with its suppliers. According to GTAT, after the company balked, Apple told GTAT that its terms are standard for other Apple suppliers and that GTAT should “put on your big boy pants and accept the agreement.”
A company the size of Apple has a lot of weight they can throw around while “negotiating” with suppliers.
