You are speaking like it was started by big companies to get free labor.
It was literally the opposite. It was started by people who wanted to share and have the source code so they could make changes and not be beholden to large companies.
You are literally complaining that about GIFTs! It is a gift that you can get the source code. You can use it, change it, learn from it. You are welcome!
You also keep associating open source to unpaid forced labor. What about hobbies?
Please tell me anywhere in the world where it is illegal to give away something I created.
It’s hard for me to believe you are not trolling. If you are not, I don’t know how to help you.
