Is it considered a sinful act and theft for several households to share a single satellite dish line without the consent of the producing company?

If the company provides cable for broadcasting channels, it is not permissible for anyone to connect it without the company's permission, because it is like electricity. It is not permissible to justify this by financial savings or by the fact that the company belongs to disbelievers. However, if the company sells and installs the satellite dish, there is no harm for the buyer to connect it to whomever he wishes, and the company has no right to prevent him unless it stipulated in the sales contract that the buyer may not dispose of his goods as he wishes, and this condition contradicts the essence of the sale. In all cases, it is a condition that what is watched from the broadcast must be permissible, otherwise, it is absolutely forbidden.
