Because Meta is releasing their models to the public, I consider them the most ethical company doing AI at scale. Keeping AI models closed under the guise of “ethics”, is I think the most unethical stance as it makes people more dependent on the arbitrary decisions, goals, and priorities of big companies, instead being allowed to define “alignment” for themselves.
There certainly needs to be regulation about use of AI to make decisions without sufficient human supervision (which has already proven a problem with prior systems), and someone will have to make a decision about copyright eventually, but closing the models off does absolutely nothing to protect anyone.
