Can you trust your hardware

I remember reading something very similar many years ago about "spying" code used in motherboard chipsets. I have little to no use for the "internet of things". IMO most of those "useful" options are just marketing points, and of very little actual use for the average person. I simply don't need for my refrigerator, microwave, toaster, and doorbell to connect to my network, and thence to the web.
