If you mean publishing open source code, they didn’t steal it. We gave it away. Generosity has always been vulnerable to “exploitation,” but some of apparently understood that risk better than others.
No, I reject this framing. Copyright violations are orthogonal to labor theft. Labor theft can include copyright violation, but it doesn’t have to. My MIT licensed code may not have been violated (it probably was though; where is the copy of the notice that my license requires?) but my labor was for sure stolen.
I am fine with people using my work, copying my source code, and distributing derivative work. I am not fine with AI companies stealing everyone’s work and renting it back to us.
My jumping off point was OSS, but I was actually talking about the entirety of human knowledge being used to make a few people insanely rich while sending everyone else who made the LLM training possible to the bread line.
