To be fair, there is a difference between saying that X demonstrates Y and saying that X proves Y. It is sometimes useful to say things like “Apple’s approach to ___ demonstrates how they approach product development.” It simply shows an example of something you believe carries over to their products. The example that comes to my mind is how the original Macintosh was packaged. Someone at Apple had taken great care to design the “Opening the box and setting up your computer” experience such that the right booklet was the first thing you saw when you opened the box, the power cables, keyboard, and mouse were layered under the documents in the right order to set them up, and by the time you lifted the computer out and put it on your desk, it all seemed very natural to plug things together and turn it on. Their attention to the details of the unpacking experience demonstrated their approach to macintosh product development in the late eighties. That being said, “X explains Y” normally suggests to me that X carries enough information that you can deduce the important things about Y from it. I wouldn’t personally suggest their marketing materials explain their products, so we agree on that.
