What is the ruling on selling and using a satellite receiver for encrypted channels?

Most encrypted channels are pornographic channels that promote evil and beautify falsehood. Therefore, selling and acquiring them is forbidden. Their seller commits a grave sin because he sells what leads to disobedience, and their acquirer is sinful and deceptive towards his dependants, as Allah Almighty says: "And do not cooperate in sin and aggression," and as the Prophet, peace and blessings be upon him, said: "There is no servant whom Allah entrusts with a flock (people) who dies on the day of his death while he was deceptive towards his flock, but Allah will forbid Paradise for him."
