It's confusing to me because charging money is implied - "we are going to have to somehow make money" - but not actually stated, and then it jumps past the revenue structure into sharing money with "rightsholders".
It has left me wondering if, instead of just charging users, they would start charging "rightsholders" for IP protection. I could see a system where e.g. Disney pays OpenAI $1 million up front to train in recognition of Mickey Mouse, and then receives a revenue share back from users who generate videos containing Mickey Mouse.
(i) they will need to start charging money per generation (ii) they will share some of this money with rightsholders
