Barter is still a form of payment and all of this screen placement occurs under contract and marketing direction from Apple. I still view that as paid product placement, which is different than if the production included Apple products without any contract or guidance from Apple.
"all of this screen placement occurs under contract and marketing direction from Apple"
Your link seems to go to efforts to state the opposite. Yes Apple has a liaison and yes they work with productions, but compared to the industry this is absolutely tepid.
So to contrast it, when you see HP or Sony or other such products, 100% of the time those companies paid a six figure+ sum and provided hardware for free. When you see Apple, the going case seems to be that you can negotiate free hardware if you want, but that's it.
