Speaking as an embedded developer (though not currently in healthcare), no device should be sold without the manufacturer's firmware. With that said, there are plenty of cases where the hardware is fine, but the software doesn't support things the customer needs for a whole variety of reasons.

Releasing more firmware as open source would be a good step towards cleaning up some of the hazmat-grade codebases out there as well.
