Even worse, let's apply the non network neutrality argument: the washer won't work without certain "licensed" detergents sold as for the safety of the washer (some claim about harm of the device from the wrong detergent).

Consumers need to outright reject these attempts by manufacturers. Is there risk that some appliances already put some sort of timer chip and stop working after some time? Kind of the HP inkjet business model?

We need some open source washer companies, I would pay a premium for an open source washing machine.
