Elon Musk would be able to pay as many women as he’d like to have his spawn, so artificial wombs to people at his level are irrelevant.

Depends what is in the contract. If the contract says devs on are the hook for any future fees they deem necessary, then the devs are on the hook. Unless they want to pay a lawyer big bucks to take on the company behind Unity with their billions of dollars of revenue and the lawyers that buys. How many indie devs do you think can afford to do that?

But are they hiring the right modders?
