1. You can't package GPL stuff into another and then sell the new product.
2. If it is required for Intel's commercial BLAS and they are giving it away for free, it would be a great loss to Intel. So whatever they are giving away must be available for free. Otherwise it makes no sense.
Edit: Open version makes use of non-commercial license MKL, which you can get anyway, see https://registrationcenter.intel.com/RegCenter/NComForm.aspx.... And most likely they are using commercial version for enterprise. But again can you compile R like that and charge for it.
