Very easy time if it's about commercial use (well, at least outside of china).

Just because AI tech bros live in a bubble of their own, thinking they can just take and repurpose anything they need, doesn't mean it should be like that - for the most case it isn't and in this case, the law just hasn't caught up with the tech yet.
