Is it permissible to work in installing satellite dishes and arranging channels when another person, in the same shop, decrypts illicit channels?

We advise against working in a shop that installs satellite dishes, because most of its users employ them for forbidden things like obscene films and lewd songs. Installing dishes for them is considered aiding in sin, and Allah has forbidden that, saying: "And do not cooperate in sin and aggression" (Al-Ma'idah: 2). And whoever gives up something for the sake of Allah, Allah will compensate him with something better.
