The problem is that the manufacturing of electronic devices has a lot of impact on our planet because of the required resources both in terms of energy and precious metals, and because of the growing pile of e-waste, and none of this is priced into our cheap gadgets.
Repairable devices means devices that live longer, which means less environmental impact, there’s nothing romantic about that.
From an environmental perspective, repair is also preferable to recycling, because reuse tends to be much less resource intensive than recycling.
