Now, if it turns out, Apple had threatened GT with financing one of their Saphire Competitors to allow them to drive GT out of business if GT didn't enter a contract with Apple - that would be heavy handedness. But there is no evidence of any such behavior.
You do understand the Apple purchased the facility for $113 million dollars of their own money, right? GT's job was to install furnaces, run them, and deliver sapphire of a particular size and quality, which they were unable to do. And, they did so with money loaned to them by Apple.
Effectively, Apple took 100% of the risk, and when things went south, GT (after their CEO made a few million dollars on the stock), declared bankruptcy and forced Apple to settle GT's debt.
Taking only what's available in the article, GT's job included running the factory, part of the process pipeline they had zero choice over, even to the point of selecting or even communicating with subcontractors (the line I quoted). When those machines in the process pipeline wholly dictated by Apple proved inadequate -- and I am not saying those are the only problems -- by necessity GT assumed at least a good portion of that risk.
You are oversimplifying the situation greatly, to the point of being disingenuous.
Apple took 100% of the risk of the new facility - it's all on Apple, GT is not on the hook for it a bit. That's why Apple did not involve GT in its construction.
GT did take risk in the building of Saphire (a risk, as it turns out, that they did not succeed on) - though they did it mostly with borrowed money from Apple (but they had exposure as well).
The Bankruptcy was mostly because GT was unable to pay back apple, and their cash flow position was such that they were no longer a going concern - but Apple is going to take a loss there as well - I can't believe that Used Sapphire furnaces are going to be sold at a premium.
The part that you bring up that is interesting, is whether the elements that Apple was building (the physical plant) were important components in the process pipeline for successfully manufacturing Sapphire. If, indeed, they were important, and if they in any way contributed to the failure of GT in successfully manufacturing Sapphire, and if, Apple indeed, did not let GT take a significant role in directing the design and build of those components - then, I'll grant you that was heavy handed behavior on Apple's part. They can't hold GT responsible for successfully delivering sapphire, but then simultaneously prevent them from having any authority over a vital component in the building of said sapphire.
Sound Fair?
Yes, we agree. And exactly what you describe is what appears to have happened.
