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.
Did they steal Wikipedia? Wikipedia is still there.
This would be true even if I signed a contract stating that I give all my labor away for free to my exploiter. You cannot sign away your rights like that, and my exploiter is not allowed to abuse my goodwill this way.
You are basically arguing in feudalism. My labor belonged to my landlord and they had full right to take all the profit for them selves.
