> any random enemy with hardware access could plug in a USB cable, flash the older exploitable signed firmware, steal your personal data, install a trojan, etc A lot of my phones stopped receiving firmware updates long ago, the manufacturer just simply stopped providing them. The only way to safely use them is to install custom firmware that are still address the problems, and this eFuse thing can be used to prevent custom firmware. This eFuse is part of the plot to prevent user from accessing open source firmware, it's just that. Your "user safety" jargon cannot confuse people anymore, after all the knowledge people (at least the smart few) has learned during the years.
