Eliminate trust.

The thing must be functional and operational by its own volition. No clouds, no hosts, no servers controlled by 3rd parties that control anything.

You do this by: 1) encryption. Make all data useless. 2) standardization. IoT devices must be compatible with multiple hosts, one being one you can install and run yourself. 3) open source (source available)

Companies can still sell their goods by: 1) offering the "thing" that must be bought. 2) offering the software or point to the software, maybe with added bells and whistles (a source-available extension, audited by FCC plus 2 other parties etc).

Control must be localized. In the app of the user etc. No round trips to any clouds.
