how about forcing tech companies to state at the time of sale how long they plan on maintaining/ updating their product/program. Also, requiring hardware manufacturers to provide an estimate of the expected lifespan in cycles of their product, and/components. Figures that are too conservative must be punished with the same level of strictness as overestimations in order to maintain the integrity of the law.

Obviously, these laws will only apply to the tech sector, but it's a start.
