> For example, the FitBit and other health trackers can do wonders for helping people get healthier, and devices like Bluetooth-enabled glucose monitors can even save lives.

Even taking these benefits as given, neither of these things need to be connected to the internet, especially not directly. A fitness application that stores your data locally and potentially offers to sync your data across devices, sure, but for these things you describe (and most IoT things, mind you), the benefits of connecting them to the internet are minimal at best.

I don't think anyone is suggesting that IoT devices store their data in some opaque format that can only be accessed on-device. However, for most of these things the model is to treat all IoT devices as dumb terminals for a cloud service, which unnecessarily has deleterious effects on your privacy and security and makes your device's utility dependent on the provider's infrastructure.
