@feld thing is - it CAN be, but most people don't even have such complicated furniture, even I don't have such, and i have a damn bluetooth table, and my old kitchen was made from ground up by me and my dad - it's not that complicated.

Electronic hardware and software however has much higher "floor" of complexity.

If you want to compare GPL and autistic screeching to something - compare it to car industry - there are plans and maintenance instructions for old vehicles - one could, if need be, disassemble and repair, or even produce their own copy of a 1966 Fiat 124. Try to repair a Tesla or a John Deere tractor an you're likely to hit a DRM, void your warranty and get cancelled on twitter at the same time. And guess what - people DO complain about that.
