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"?

The same way that Fitzcarraldo stole the labor of the Amazon Indians when they moved the ship over the mountain in order to profit from the rubber.

Previously when I licensed my code with a liberal license I got something back, credit, contributions, connections, job opportunities, etc. The AI companies stole my labor, then they demanded I pay them, and finally they took my job.
