Because as much as I appreciate you desperately want to believe, ultimately PGMOL is a private business with employees doing normal jobs, not one of whom have heard or accidentally been CC’d into an email and leaked any details of this secretive scheme, which any journalist would blow the budget to get hold of.
Neither have any of the referees, linesman or fourth officials involved ever had one too many sherries and spilt the beans to a friend or family member. Indeed the closest we have come is refs saying they’ve been asked to retrospectively change their reports *after* games to reduce or increase suspensions based on Sky’s editorial line.
Of course it could be that Howard Webb has bought every ref a Bittium loaded with Encrochat to give them their orders and keep this nefarious scheme deep under wraps, but not even Mulder and Scully would take that one on, and I’m sure as much as we may not agree on this topic, even you don’t seriously believe it in your heart.
