We should have the ability to run any code we want on hardware we own

It's a matter of ownership vs. licensing. You own the hardware you buy, but you license the software. I agree with the author that as long as you use that software, you should be subject to the constraints of the license.

The key is that if you choose not to run that software, your hardware should not be constrained. You own the hardware, it's a tangible thing that is your property.

Boils down to a consumer rights issue that I fall on the same side of as the author.

The hardware should not be equipped with undefeatable digital locks. Put a physical switch on the hardware (like Chromebooks have-- had?) to allow the owner to opt out of the walled garden.

Also worrisome are e-fuses, which allow software to make irrevocable physical changes to your hardware. They shouldn't be allowed to be modified except by the owner. (See Nintendo Switch updates blowing e-fuses to prevent downgrades.)

E fuses are needed so people can't downgrade the device to old insecure software to exploit it. Without it or an equivalent like a secure monotonic counter how do you think such attacks be protected?
