On the contrary, you cannot mathematically distinguish (c)opywrong laws as anything but a kind of slavery.
Define a person A as a slave to person B if person B has legal control over person A at all times.
Now imagine person A is hanging out with Person C. With (c)opywrong laws, Person B has legal control over a subset of person A's behavior in this scenario (they are forbidden from sharing certain files with Person C by Person B). Hence, Person A is a partial slave to Person B.
It is not metaphor, it is literally a subset of the same thing. Intellectual Slavery is just slavery from many masters.
