I don't see how it's more environmentally friendly to replace existing energy grids with sustainable versions if we still demand more energy from the environment to begin with, especially for something that's in the pursuit of trying to make more money and that money ultimately gets spent on things on things that violates the 3 Rs. I'd rather a company who claims to commit to green initiatives do it throughout the entire stack, which includes not encouraging (i.e., providing the option) to mine.
Or in another way, I don't see how it's better to replace a coal plant with swathes of wind and solar, because those have their own environmental problems. If we want to be more mindful of our environment, we should do our best to reduce our impact overall.
It's the same kind of criticism Apple gets. How can they claim to be a "green company" when they want to destroy the right to repair?
