Perhaps compulsory software updates at least as far as security issues for a reasonable time frame after selling a particular device as new to stores. I'd say 5 years to go with the 5 year warranty against defects in manufacture. This would discourage waste and improve the second hand market.

So moto, samsung, et all would be obligated to provided fixes for 5 years after they sold the last unit. If an oem can't meet that obligation just forbid their import.

We presume a right to the product of other people's labor for the privilege of doing business here all the time. See every product in existence.
