Fun fact: Copyright is also the basis on which you enforce copyleft provisions such as the those in GPL. In a world without copyright, there are no software licenses yet alone copyleft.

I know it’s very challenging for “this community” (FOSS users & developers let’s say) because a significant number of them also support shadow libraries such as Sci-Hub and Library Genesis and Anna’s Archive so how do we reconcile “copyleft (therefore copyright) good” with “copyright bad”?

I don’t have a clear answer yet but maybe the difference is as simple as violating copyright for personal purposes vs business purposes? Anyway…
