That professor saying that the use of work he already produced amounts to "slave labor"... copyright infringement is substantially different than slavery.
"Slave labor" doesn't always refer to chattel slavery.
> any coerced or poorly remunerated work. [1]
FWIW he's primarily known as a writer of fiction and memoir, not as a professor. Interestingly, half of the other professors named are fiction writers.
Uneducated and privileged take by the professor.
Not talking about that professor in particulier, but it seems like there is a significant amount of "slave labor" happening in academia, by professors, that goes further than simple copyright infringement.
I am talking about professors taking the work of their students as their own, unpaid of course, and the students can't say much because their future depends on it. So before calling simple copyright infringement "slave labor", they should look at their own community. At least the professors whose work is illegally copied are not forced to do it by the ones taking it.
