Re: All well and good..
The business model of certain companies relies upon selling a cheap and irreparable device that is deliberately engineered to have a lifetime that will only exceed the warranty period by the time required for a politician to forget an inconvenient fact.
As the disposal of this device is then via sticking it in the local dump's recycling section the costs are carried by the local council, not the consumer or suppliers. Therefore, the customer doesn't care, the supplier doesn't care, the supply chain doesn't care and the manufacturer doesn't care. Pretty much all equipment looks like this now because everybody else has either been driven out of business, has adopted this business model to compete or they produce a niche device that is not capable of competing in the mass market.
As soon as the costs are attributed to anywhere other than where it is at the moment then people are going to start caring.
If the supplier of new equipment is required to collect and dispose of the old device at their cost then the awful manufacturers still wouldn't care; people don't tend to deliberately repeatedly buy shit equipment so chances are that the people paying to dispose of the cheap unreliable equipment wouldn't be the ones making, stocking or supplying it. This would be an awful idea, IMO.
However; If the supplier of the original equipment that broke gets the bill (or their supplier in the supply channel, should the end seller go out of business) with a waiver for if a device has a repairability score of less than 10, then what would you expect would happen?
Suppliers wouldn't want to import, transport, warehouse or stock anything with a repairability score of less than 10. The supply chain as a whole would quickly start considering considering handling containers full of lower quality kit with all the enthusiasm of an equivalent weight of radioactive waste. At the very least, prices of touching anything from that container would rise massively to cover the anticipated risk of it arriving back to them in the future. That would immediately mean that "cheap" irreparable devices with expensive recycling costs would rise in cost to the point that actually they weren't cheap anymore and would be displaced in the marketplace by more repairable equipment.
