Z-Library Helps Students to Overcome Academic Poverty, Study Finds

> Z-Library, or a similar website, is helpful to students living in poverty (82% agree).

I would really like to hear the reason for the 18% who thinks that it is not helpful for poor students. Is it this complicated argument that they will discourage authors from writing books and then this will hurt all students in a hypothetical scenario? Or there are other reasons?

I mean I understand that some people will just want these sites gone on IP grounds or because it is against the law ..etc. But this question was different.
