What's your source on this? In book publishing the publisher is absolutely responsible if their author plagiarizes. I'm curious how copyright law affects code differently.
Generally that's how liability works. And presumably any competent company would write a guarantee into the contract that the developer would have a right to use any code they put into the game. Do you have any source that says otherwise?
Don't fuck with them Bethesda lawyers man.
Seems highly unlikely that Bethesda would just sue the developer and let the game continue to make money whilst using their technology without some sort of reimbursement and likely either forced licensing of the tech or shutting down the game. WB will definitely be affected.
WB might be affected, but it's not that simple.
