How can one absolve themselves from the sin of downloading and watching a large number of programs and films, which are intellectual properties, and which was done for years without the ability to count them or return the money to their owners?

Scholars differ regarding the consideration of intellectual property rights. The prevalent opinion we adopt is that they are to be considered absolutely. Therefore, you must estimate the value of these rights and dispose of them by spending them on charitable causes, if you are unable to deliver them to their owners or seek their forgiveness. As for watching TV series and movies, you may refer to the relevant fatwas.
