It's definitely a gray area in some countries.

A few decades ago our family got a 'proper' company with a shop front to install a satellite dish for us. We were then able to watch the Sky Tv from the UK even though we were not based in the UK (we still paid for a subscription but it was billed to a proxy address). This was the 'gray' part of what the company was selling.

What they also sold was sattv boxes with integrated decryption that would allow you to watch pretty much any European Pay TV (albeit not Sky, as they used a more robust encryption scheme) for free. They never mentioned the legality of it but they definitely advertised it as something they openly sold (in shop and in their ads).
