You are somehow conflating "massive corporation" with "independent creator," while also not recognizing that successful LLM implementations are and will be run by massive corporations, and eventually plagued with ads and paywalls.

People that make things should be allowed payment for their time and the value they provide their customer.

An LLM is not a person, it is a product. It doesn't matter that it "learns" like a human - at the end of the day, it is a product created by a corporation that used other people's work, with the capacity to disrupt the market that those folks' work competes in.
