Blocking the Newcastle takeover on the grounds that someone in Saudi Arabia is pirating Bein is the same as blocking Sheikh Mansour's takeover of City on the grounds that, as Deputy PM of the UAE, he's responsible for the war in Yemen.
Or blocking Abramovich as Chelsea owner on the grounds that, as a Putin confidante, he's responsible for the Russian annexation of Crimea. In fact Abramovich isn't even allowed to remain in the UK and is a direct target of the UK Intelligence agencies as a result of Russian sanctions. He can only visit as an Israeli citizen and can't have anything to do with the running of Chelsea.
They're not the same thing at all. If a company called Addidos were operating out of India selling knock off Man Utd, Chelsea and Sheff Utd gear all over the world and those clubs contacted the Indian government several times to try shut them down and where told to get fucked each time, that would be similar if India came looking to buy Newcastle. An Indian individual could purchase them no problem, but the state itself would be politely reminded to get fucked.
