List of petitions against OpenAI's for-profit move

Apr: Californian civil society nonprofits

This petition has the most rigorous legal arguments in my opinion.
 

Others I know also back a block (#JusticeForSuchir, Ed Zitron, Stop AI, creatives for copyright). What’s cool is how diverse the backers are, from skeptics to doomers, and from tech whistleblowers to creatives.
