the article in gulf times was against boxes like Dreamboxes through which you can watch paid channels without subscribing to them. Govt is studying the ban on such boxes.

In case of Tata Sky, you are paying the provider the regular monthly subscription charge. However, Tata Sky may take action against you since its not allowed to use it outside India.

So, its not illegal in Doha to use TataSky but illegal in India to use the box outside India.
