I don't care a lot about the deeper artistic value of this all, but I haven't seen anyone deny that this design is very polarising. Much more so than the visual style that has been used in previous WWDC slides.
The question remains whether a polarising design makes sense for things like developer sessions, or Apple's "iOS for businesses" website a while ago. If not, then it might technically be good design, but used in the wrong context.

Yes, but polarising is not necessarily bad. It actually means "some think it's bad, some think it's good, and all think it's interesting enough to talk about".

Well, since they went with this aesthetic for iOS7 they will have to be consistent for their other iOS related material too.
You could show them the work of great Swiss designers for example, and they would think the same.
