NonprayingMantis: The legal/illegal thing is interesting too.
I don't believe it has ever actually been tested in court, and all we are going on so far is some lawyers opinions based on interpretations of various other laws. Laws that were written long before video streaming became a 'thing'.
It's hard to argue it is definitely legal or illegal right now. It seems probably legal, but we can't be sure.
I don't think it needs to be tested in court. There really isn't any argument that it is illegal. Sky are crying 'illegal' but aren't backing that up with any kind of legal opinion as to who - because I don't think there is one.
