YouTube is part of Alphabet, one of the biggest corporations in the world. It can easily afford to pay people. It isn't co-operation, it's a corporation which takes the work of other people and makes lots of money off them, without paying them properly (or at all in many cases). Wikipedia's content is used by LLMs and other such outlets who also profit off unpaid labour.

It is a basic right of people to be able to afford to live. It's easy to work for free when you have family money but you cannot support yourself when you don't.
