It's just a vague guess, but checking this
page a possible explanation came to my mind. The original AmigaONE was an A1200+AmigaONE mobo fitted together, so the Magic Pack was intended for the A1200.
Now, there is 2 possible scenario: A., in the long time passed by they have obtained a new license, B., in the long time, pressure they had endured, they've just forgot it. When the AmigaONE project started all licences were all right.
I don't see intentional wrongdoing even in the latter case.
