The main reason is most likely because that is how they want to do it. But all these fine radios do not provide you with the information and source code so you could make your own modifications, a huge difference to many when compared to FlexRadio and their open development. Being open was a risky decision for Flex but it has allowed people on the outside to make contributions. History has shown that it was a good decision, not just for them but for owners of the SDR-1000 also.
