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.
If it is really possible to stop climate change by banning bitcoin mining or converting bitcoin to POS however they want, I would agree with them. But it's clear that climate change is caused by a lot of pressure from hundreds of different industries, bitcoin is not the only cause of climate change. Many people think that other industries create use value so emissions are acceptable, but so does bitcoin, it doesn't give them value but it gives value to millions of other people. Therefore, this can be considered a conservative, incorrect argument. This is yet another excuse for bitcoin haters to take advantage of mining to put pressure on bitcoin.
