There's a lot of space dedicated to laying text over pictures proving that the words are weak enough that a big image, possibly unrelated, is really important to obscuring the message. Give me something to feel before I try to think about the content.
Even when done well, words overlaying images means that neither is quite important enough to stand on their own and the added complexity of dealing with making it work and curating it, when the content manager doesn't know one of the more technical 'rules', means constant intervention from technical or design support.
Images, when not adding value are distractions from the lack of value in the content and add to the download size and content handling complexity (slower, less usable, higher dev costs).
Good design is hard enough vs. following Apple style guides for "light from the sky."
