For two - they can't do shit. Every one of those businesses can try to pivot into being the next OpenAI, but even OpenAI can't be fucked to turn a profit. They can't retract their models (remember Llama 1.0? hahahahahahahahaha) and they can't piss and moan to the authorities when their weights leak because 99% of them contain unlicensed copyrighted material in the first place.
The real twist to this Gordian knot? Open source is the only model you can release conventional AI under, because anything else precludes a Fair Use defense. Everyone that has "proprietary" models only manages it by playing keep-away with the community.

Five year old children know that they can keep their toys once they stop selling them at Wal-mart. Pulling a model off HF doesn't stop new finetunes or even redistribution and re-quantization of the old model. Mistral and Runway can do whatever they want, all their models are belong to us.
