I've read the "FAQ Why must IoT Inspector upload the data to Princeton?" and do understand the reasons for data collection, maybe once it reaches a data saturation point this new option could be introduced (I believe there is a “Start/Pause Inspection” button but that seems to only temporarily pause collection).
Naturally, there's going to be some reluctance in using and deploying a tool that uploads data to an outside party.
