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.
Stealing labor itself isn’t actually a thing. Your wages could be stolen, except - what wages? Maybe the output from your labor could be stolen, but not if nothing material was lost. If you can’t point to a specific intellectual property violation, you have no case.
Did they steal Wikipedia? Wikipedia is still there.
You already valued your own labor at zero by giving it away for free. How is taking something you give away for free suddenly considered "stealing"?
