Must an Internet service provider filter music websites, even though subscribers reject that, and it may lead to the company's loss and customers turning to other companies that do not even filter pornographic websites?

A Muslim must be keen to earn lawful money, according to the hadith (definition): "The feet of a servant will not move on the Day of Resurrection until he is asked about his life and how he spent it, about his knowledge and what he did with it, about his money - from where he acquired it and on what he spent it, and about his body - how he wore it out." Earning lawful money is a cause for blessing, provision, and answered prayers, while unlawful earning eradicates blessings and prevents prayers from being answered. The company must be closed to music, because it calls to immorality and decadence and weakens faith. Allah blesses the pious and provides for them from where they do not expect.
