plain and simple.

 Film makers, associated staff and their funders spend years and cash producing a product to bring to market for sale - this feeds their families and benifits the economy of everyone. If you aquire that product by paying another party (in this case Newzbin) a small amount for a product that does not belong to them, you are not only guilty of recieving stolen goods but are encouraging the continued theft of future products.

This is not about censorship but about theft. You would not like it if your hardworked for property was stolen - why do you think it is just to steal anothers property?
