I don't agree, and moreover I note that this is a purely semantic point that you are making.
Apple is a major hardware manufacturer and software developer, and it seems totally appropriate to suggest that Apple is responsible for how it chooses to implement certain features. Saying "well, we just took it off the shelf" may work for a small-potatoes business, but not the largest public company in the world.
Additionally, it's like the Nuremberg Defense of software.
Any protocol (or tool in general) is appropriate for certain situations, and inappropriate (in this case, vulnerable) in other ones. You shouldn't suggest that others must bend over backwards semantically to try to pass the buck away from Apple, because Apple is responsible for using the protocol. Saying "Apple's protocol" indicates that Apple made the conscious choice to use that protocol, and that Apple has ownership of the consequences of using that protocol.
