The mistrust comes from those doing it, and the clearly corrupt ways they are operating. The maggot movement is basically rooted in a lot of very real frustrations from very real longstanding problems, but the only thing it offers as solutions is performative vice signalling.

People who care about the problems of digital security are not going to lean into the idea of simply banning devices based on where they were manufactured. Rather they would work at general standards and solutions to actually solve the problems - things like untying the markets for hardware/firmware/services, requiring firmware source escrow, mandating LAN protocols and controllers so every single IoT device isn't backhauling to its own mothership, and so on.

Likewise people who care about domestic manufacturing first and foremost are not going to champion applying steep blanket tariffs two decades after all of that industry has already left, or using regulatory agencies to shake down manufacturers for unrelated concessions.
