This is a very good idea! But how would we enforce and check this (see recent issues to enforce right to repair)? What would be the KPIs - repairability score? Apple for example is arguing against this by saying that when they repair things themselves it is more sustainable than making documentation available to external repair stores (Louis Rossmann has been talking about this for ages)
This is too sensible of an idea to ever happen, though. Nearly every time a discussion comes up about this, the companies essentially argue that their right to fill the world with ewaste trumps all.
