Hm, that doesn't help. I guess that's their way of trying to avoid knock-offs of their kits but it definitely takes the fun out of trying to figure out how things work if that part is pushed into some kind of black box.
But it is also a sign of the times, rather than having a bunch of logic the quickest way to get some project off the ground is to tie the i/o to a microcontroller and solve the remainder of the problem in software.
