DRM offers many bugs for an optional feature. I think they realized that the product testing requirements for DRM are so onerous that they'll never be willing to comply. Theoretical example:
"The patient died when the hospital was locked out of the pacemaker due to a bug in the license code parser in the patient's device."
You still need to have security for remote control safety, but a device maker cannot afford even a single bug in the "I have my hands physically on the device and I require access" pathway, or else deaths will eventually occur.
My understanding is that they are partnering with those companies. For instance, Medtronic produces the 670g, the commercial closed loop system (what I have)
