So FOSS Devs using ChatGPT are taking them...how?

Yeah, you can't, because it's not claimable, it's proprietary software, even the "open" models are restricted in their licensing and usability.

Perhaps local models will make some positive difference in the future, but likely not. I suspect that decades down the line, we will see LLMs in a similar light as asbestos or Teflon. Things that were hailed as "miracle products" that seemed amazing at first, but had incredibly destructive side-effects that we only found out about long after the proliferation.

If something is overall destructive to society, I don't want to "take" it, I want it gone.

I don't want worker-owned casinos, or online gambling markets, or cigarette companies, I want those things gone. They don't make us better off or more free, they harm and enslave us.
