They're certainly not the first to do it. I've got loads of matches filmed by Mike Bennett at Wolves where how much of the action you saw depended on who happened to be operating the camera at the time. If it was his regular cameraman then you'd see it, but if he was away they used to borrow someone who would normally only film the greyhound racing and they would religiously follow the leader, with Bennett amusingly berating him during his added commentary, "we did try and explain to him not to follow the rider at the front!".
If anything, it's the abysmal drone camera that annoys me. It works very well on replays, but there's no need to use it during the live broadcast.
