The answer to that is simple: They hate AI and the environment angle is just an excuse, much like their concern over AI art. Human psychology is such that many of these people actually believe the excuse too.
It helps when you put yourself in the shoes of people like that and ask yourself, if I find out tomorrow that the evidence that AI is actually good for the environment is stronger, will I believe it? Will it even matter for my opposition to AI? The answer is no.
You don't know that. I don't know about you (and whatever you wrote possibly tells more about yourself than anyone else), but I prefer my positions strong and based on reality, not based on lies (to myself included).
And the environment is far from being the only concern.
You are attacking a straw man. For you, being against GenAI, simply because it happens to be against your beliefs, is necessarily irrational. Please don't do this.
> I prefer my positions strong and based on reality, not based on lies (to myself included).
Then you would be the exception, not the rule.
And if you find yourself attached to any ideology, then you are also wrong about yourself. Subscribing to any ideology is by definition lying to yourself.
Being able to place yourself into the shoes of others is something evolution spent 1000s of generations hardwiring into us, I'm very confident in my reading of the situation.
> Having beliefs, principles or values is not lying to oneself.
The lie is that you adopted "beliefs, principles or values" which cannot ever serve your interests, you have subsumed yourself into something that cannot ever reciprocate. Ideology by definition even alters your perceived interests, a more potent subversion cannot be had (up to now, with potential involuntary neural interfaces on the horizon).

I will not be providing one, but that you believe one is required is telling. There is no further point to this discussion.
