> Z-library were in it for commercial gain (you could access a certain number of books but to get more you had to pay for a subscription). They started out as a fork of library genesis, whose mission has always been strictly non-commercial and about providing free access to everyone without limits.

What is the difference between what "z-library" was doing, which was "you download a lot for free, but if you need more, just pay us, because no internet bandwith is for free" from donations? I always understood the subscription at z-library as support, not different than patreon...
