There are a lot of people hacking on insulin pumps and they are lightyears ahead of commerce. If you want a very interesting rabbit hole to dive into try 'artificial pancreas hacking' as google feed.

I would trust the people that hack on these systems to be even more motivated than the manufacturers to make sure they don't fuck up, it's the equivalent of flying a plane you built yourself.

I would think it's the opposite. People that hack on this only risk their own life. Companies risk many people's lives and will get sued. Of course the person doing the hacking doesn't want to die but they're also willing to take the risk.

A great analogy because people die that way. I personally would never push code to another person’s insulin pump (or advertise code as being used for an insulin pump) because I couldn’t live with the guilt if my bug got someone else killed.
