The CPAP jailbreak community was eye-opening when I first learned of it. I never expected something like that, but with the draconian policies it's not surprising.
For example, my CPAP has a CDMA radio inside, which transmits usage data back to the manufacturer & my doctor. Insurance won't pay for it unless the machine tells them I'm using it – so a medical device company has a record of when I sleep and wake, which is mildly unnerving.
Edit: I think sleepyhead[0] was the biggest project when I started looking into it, but it isn't under active development anymore. Apparently forked to OSCAR[1].
