But isn't this just providing for hardware decoding, where (presumably)
the hardware vendor arranged for whatever needed licenses?
It's really not that simple, IANAL but AFAICT the licensing costs
comes down to who provides a complete solution, the HW doesn't provide
that so they may not be required to arrange the licenses.
