I'd be fine with that if that was the way copyright law had been applied to humans for the last 30+ years but it's not. Look into the OP's link on clean room reverse engineering, I come from an RE background and people are terrified of accidentally absorbing "tainted" information through extremely indirect means because it can potentially used against them in court.
I swear the ML community is able to rapidly change their mind as to whether "training" an AI is comparable to human cognition based on whichever one is beneficial to them at any given instant.
