One-eyed selectivity
Note the woketivists didn't pick on the far more relevant mineral to all these manufacturers: Coltan. Of which virtually the whole world's supply comes from the congo. No differences in practices, between minerals.
Possible reason?
Solar power is effectively impossible without coltan. And it needs relatively large amounts of it.
.
(As an indication:
If we used solar for 100% earth's power needs, we'd completely exhaust the world's reserves of coltan in a shade over 4 weeks (8% of annual reqts). A further 2 key minerals are eliminated by 12%. Solar is actually the least renewable of any energy supply, making coal's second-worst case of centuries look luxurious.
Problem: essentially all our hightech stuff nowadays utterly relies on coltan. Your smartphone, your laptop. The lift's circuitry, your car's engine mgt, the traffic lights. Your washing machine, etc etc etc)
