Yes, for sure. Some people explain it away as "well if you buy Wrangler jeans from Walmart and there's something wrong with them you ask Walmart for a refund." So if you buy X's app from Apple you ask Apple for a refund. That kind of makes sense. But if Wrangler does a recall, they have a way of getting that across to their customers.

I think you might also want to revisit your relationship with Apple Incorporated.
