Yeah... who doesn't love moral absolutism... The honest answer to all of these questions is, it depends.

Are these tools ethical or environmentally sustainable:

AI doesn't just exist of LLMs, which are indeed notoriously expensive to train and run. Using an image generator for example can be done on something as simple as a gaming grade GPU. And other AI technologies are already so light weight your phone can handle them. Do we assign the same negativity to gaming even though it's just people using electricity for entertainment? Producing a game also costs a lot more than it does for an end user to play. It's all about the balance between the two. And yes, AI technologies should rightfully be criticized for being wasteful, such as implementing it in places that it has no business in, or foregoing becoming more efficient.

The ethicality of AI is also something that is a deeply nuanced topic that has no clear consensus. Nor does every company that works with AI use it in the same way. Court cases are pending, and none have been conclusive thus far. Implying it is one sided is just incredibly dishonest.

but do they enable great things that people want?

This is probably the silliest one of them all, because AI technologies are ground breaking in medical research. They are seemingly pivotal in healing the sick people of tomorrow. And creative AIs allow people who are creative to be more creative. But they are ignored. They are shoved to the side because they don't fit in the "AI bad" narrative. Even though we should be acknowledging them, and seeing them as the allies they are against big companies trying to hoard AI technology for themselves. It is these companies that produce problematic AI, not the small artists, creatives, researchers, or anyone using AI ethically.

but are they being made by well meaning people for good reasons?

Who, exactly? You must realize there are far more parties than Google, Meta and Microsoft that create AI right? Companies and groups you've most likely never heard of before, creating open source AI for everyone to benefit from, not just those hoarding it for themselves. It's just so incredibly narrow minded to assign maliciousness to such a large group of people on the basis of what technology they work with.

Maybe you're not being negative enough

Maybe you are not being open minded enough, or have been blinded by hate. Because this shit isn't healthy. It's echo chamber level behaviour. I have a lot more respect for people that don't like AI, but base it on rational reasons. There's plenty of genuinely bad things about AI that have to be addressed, but instead you have to find yourself in a divide between people cuddling very close with spreading borderline misinformation to get what they want, and genuine people that simply want their voice and concerns about AI to be heard.
