Does it? How so? Can you clarify the connection? Apple does re-use hardware, so isn’t that evidence they don’t agree with you? Doesn’t it mean they believe reuse is good for their brand and not diluting sales? Maybe - since they do both (reuse and recycle) - this has nothing to do with choosing one over the other, and it is more about choosing between recycling vs landfill, ensuring proper managed disposal?
They're suing for damages (to them, Apple) because of reuse in lieu of recycling. Not including the money they made. Apple believes this act damaged them. The connection is laughably obvious. Unless Apple shipped unsecured private or proprietary information on these devices to the recycling company, I don't know what other possibility you can think of. Your counterargument is a resale market entirely controlled by them wherein they can pick and choose every item.
They’re suing for the amount that GEEP made breaking their contract, plus some punitive damages. That seems like it might be par for the course in a contract dispute. Breaking the contract does damage Apple in a number of ways. You seem to be making assumptions about which ones they care about most, without evidence, and in contradiction to what they’ve done and said.
You said “Recycling is better for your brand than the environment. Reuse dilutes your brand and reduces sales.” How does Apple’s control of their resale (reuse) market prove your point here? It seems like the point you just brought up contradicts what you said earlier. Control of their resale market is evidence that it’s an important channel, that they care about it, and that they have strong reasons to prefer resale to recycling, no?
Compare the numbers recycled or otherwise disposed of to the numbers reused. they will only reuse through their own channel so they can pick and choose the reuse that will strengthen their premium brand image. It's the same practice as having licensing for repair and distribution. They only want people that they think help their brand identity and image. Otherwise they would be fine with general right to repair.
