Borderline strawman there but I'll bite.
Open weight models trained unethically are unethical. Closed weight models trained unethically and then sold back to you for a profit from gas-powered datacenters funded through Ponzi schemes are substantially more unethical.
From there it's a harm reduction calculus. No, those are never pleasant.
So do you let the closed weight labs conquer the field unopposed just so you can feel better about yourself? That's a valid stance, FWIW, and it's also super easy and convenient because you don't have to do anything. It especially makes sense if you believe it's still possible that AI will just go away on its own. I don't, myself, not anymore, so I encourage the use of open weight models, however grudging, so people don't give money to the closed labs and in the worst case aren't eventually stuck with the maximally unethical options. And we've not even touched on the nightmare labor replacement scenarios that seem every day less unlikely. Am I right? I have no clue. Like you, I'm just trying to make the best choices I can in a world that's gone to shit. I'd recommend dropping holier-than-thou attitude either way, though, because it doesn't help our side. Man.
