Looking into this a bit more, it looks like both of the use cases they’re concerned about are pretty edgecase-y.
They’re worried about users not getting glucose notifications. And the user has to intentionally turn off notifications in a settings panel for one use case, and for the other use case, a caregiver must intentionally opt into a hidden accessibility mode that is literally designed to turn a smart phone into a dumb phone.
This smells like the Abbott legal team is being overly cautious.
