Isn't it though? To me, the rephrasing doesn't invalidate the point.
It does. You might disagree with the idea that we (collectively) don't care about environmental damage, but it doesn't make the counter-argument about us generally not caring irrelevant. Which is what a whataboutism is all about.
The argument "AI is contributing to the climate crisis" can be absolutely countered by "we don't value a technology on the basis on its climate impact."
The latter argument might be false (and you could argue to demonstrate that we do care and we have banned convenient technology with no easy replacement based on energy cost concern), but it can't be dismissed as irrelevant.
