I see this the same way. The TOS states that you are not allowed to use an intermediary layer to call the iPhone OS API. A C++ or C library that would abstract the underlying OS' API would clearly be such an intermediary layer and if there would be sort of a QtMobile or wxPhone or whatever framework that would allow you to write cross platform mobile applications in C++, Apple could ban it based on their new rules - even if you were sticking to the approved set of programming languages.
