On balance, open access helps the developing world far more and costs less: Because access to journal and conference articles is now possible. Before open access, article fees around $50 for reading a single article meant, that to write an article you had to spend the $500 on the roughly 10 (usually more) related articles you needed to research and reference. To even get to the stage of writing an article, you need to read quite a few, impossible with the sky-high subscription fees that even rich western institutions balk at. And as everywhere, university libraries reimburse publishing fees out of the subscription cost they saved.
Open Access is cheaper, fairer and especially beneficial to education in the developing world.
Of course reading articles costs nothing on SciHub, but I guess the people you are working for don't want that to be known, eh?
