I wish they spent money on something more meaningful, not on ads against PoW. Some are fast to attack Bitcoin because they don't like it much, don't understand it, and think they can succeed if they go against it. That's not possible, the consensus to move from PoW to PoS won't be reached.
Climate change is real, but fighting Bitcoin won't stop it or even meaningfully make the problem smaller. There are plenty of other areas where meaningful change is possible and where advocating for change would make more sense.
Also, it would be nice if they did their research to prove that if they succeed, things will actually get better and it won't be that the dirty energy Bitcoin used would immediately get used up by other players, so it won't even make that tiny difference it's supposed to make. And, on the contrary, I've heard interesting arguments that Bitcoin can actually stimulate switch to green energy because it can be what creates demand for it.
This is exactly the issue. First off, I'd argue supporting a currency, with electricity, that divests away from proof of war (the $USD / $EUR / etc), is much better for the planet than not doing so.
But that said, the biggest issue is what you already said, dealing with opportunity cost. Even if they were correct (they aren't), there are things that they could battle against with a much higher saving-the-planet-ROI.
Total nonsense. It's so bad I have to wonder if it's a government co-opted plant.
