I’m pretty free-market oriented but I think this might be the right answer. If you sell a network-connected device you should be on the hook for at least security updates for 10 years.
Good free-market solution is to price-in the cost of manufacturing emissions and eventual disposal of the hardware into the sticker price of the device by e.g. a pollution tax assessed by a regulatory agency on a per-item basis.
Manufacturers will then be incentivized to make and support lasting hardware as consumers get averse to paying the pollution tax repeatedly. (And, they will try to make more sustainable hardware that gets assessed less tax in the first place).
I don't think this kind of solution works to be honest. This creates a right to pollute or generate waste more than focusing on solving the original problem.
Having clear regulation and forbid this kind of practice that apply to everybody, not just the poor.
A tax would not solve anything, it would just give a free pass to the wealthier part of the world to pollute and generate waste. The wealthy parts of the world are the biggest source of waste and polution in the first place.
It would also allow powerful companies to bargain between countries and continue playing the dog and cat game they've been doing. Trying to force companies like Apple or Gooogle to pay existing taxes is already a lost cause. Those companies don't care about it and would rather invest in avoidance schemes.
On the contrary, if you hit where things are sold, like closing a whole market like the EU until you abide to a regulation, like the one mentionned in my comment, is much likely to have a real impact, and would be much faster to.
