Possibly there is a per-unit royalty for the MQA-developed code which was too steep (I can't imagine it was because the code was not of sufficient quality). As long as it is a sanctioned implementation there is no reason why they shouldn't get a blessing from MQA. There is an interesting question if they have access to the certificates which enable authentication (lack of that shouldn't actually prevent the decode).

Low-mid cost consumer electronics is price sensitive, if MQA are charging too much for decoding software this could be a limitation to mass adoption.
