Even in the event that it is proven that the IME is collecting telemetry and has all these spy capabilities, how do you think it's going get traffic out to the internet?
Particularly if the computer is airgapped then there is nothing to worry about.
Nothing to worry about
yet! How long will it take before every device has it's own (low bandwidth) data connection to "phone home" even when the user doesn't connect it? €2.50 is all it takes:
I googled it, and the first thing I found was lifetime eSim for €2.50, to be soldered inside a device. This is very scary, it will create a whole new level of attacks. Imagine replacing someone's hardware wallet with a fake device with esim that instantly broadcasts the PIN. Air gapped devices will need a faraday cage to be sure.
