Are you suggesting that the change is too slow/not drastic enough? Or perhaps that a change isn't taking place at-all in the first place, that it's all just hot air?
I say that anything less than that is worse than useless, because we're spending wasted effort (mindshare, attention) when time is, to the best of our knowledge, running out.
Now i don't know that personal activism and moral campaigning will be insufficient in this case, it just smells that way to me. It also has a certain fragrance of moral superiority and virtue signalling about it, which i guess triggers me, or something.
