Cellular operated iot networks are power hungry and $ expensive. Both provide insulation from unwanted tracking.
A pervasive network that can be accessed with a couple dollar IC with minimal power that’s hidden from user would be much harder to escape.

Not anymore – I believe NB-IoT is already within an order of magnitude of unlicensed IoT (i.e. LoRa, 802.15.4 etc). Expensive? That's relative, but what makes you think that Amazon is giving away Sidewalk for any less? AWS is not exactly known for their low prices.
- qazxcvbnmlp 3y agoHard to answer this question with specifics as sidewalk is still in development. Observations are my own, from when I developed devices using LoRa and nbiot. In general, NB-IOT is operated by the cellular companies and has associated reliability expectations. Additionally the cruft leftover from it being a cellular product really added to complexity and cost to implement. Unlicensed spectrum has much lower reliability, and I would expect them to charge less accordingly.
