Then the answer is "no" because there has not yet been a system made that RMS will not nitpick in some way or another. The microcontroller that runs the LED on the back of the screen will not come with source code and so forth.
The case of the toaster is very clear: we can't tell,
except by taking it apart, whether it has a processor and
software or a special-purpose chip. Since that we can't
tell the difference, it makes no difference: therefore, a
program that will never be changed is equivalent to a
circuit. I don't care whether a toaster or microwave oven
contains software.
In your example, unless the microcontroller which controls the LED can be upgraded, then for all intents and purposes, RMS considers it a circuit which cannot be modified.
One need to look at it from the perspective of property ownership rather than inherent ability of the device. If someone has bought a device, at that point they should be in control of the property. If the manufacturer can exert control which you don't have, then they are de facto owners of the device after sale.
Its the difference between me selling you a computer you own and control, and giving you a user account while retaining root control for myself. The first is a sale and transfer of ownership, and the other is me renting out cloud access. From a perspective of rights, liberty, autonomy, control, and privacy, a toaster and a TiVo is two completely different kind of devices. One is your property which you control, and the other is someones else device which you have bought permission to use.
Last, let me clarify with an example. Let say I rent you a coffee machine on indefinite period of time, on the condition that you pay me $1 per cup. Simple concept, common practices in many offices, and it is easy to understand who the property owner of the device. Now lets change the setup by actually selling the device to you, but where DRM restricts the device so only my coffee is permitted, which just happens to add an extra cost of 1$ per cup compared to other brands. Has anything actually changed?
