How can one reconcile fatwas that prohibit intellectual property and the copying of computer programs with the presence of audio materials and books belonging to production companies on a website, which prevents these companies from benefiting from their profits?

The audio materials and books uploaded to the site have been acquired legally with their copyrights. As for the consequence of their publication, which may reduce the profits of their producers or publishers, this is sometimes a donation for the dissemination of good and the attainment of reward, and sometimes it is in exchange for a financial compensation received from the site.
