Might be different in the UK for responsibilities. But an A380 taxiing onto stand would have loaders nearby the nosewheel awaiting chocking when the aircraft stops, with access to a stop button on the stand guidance stanchion, if fitted. There may be wing walkers guiding the aircraft onto stand (fail).
Have a look at the first picture again. Looks like there's an airbridge closer to the aircraft than the one that's hit the wing. I wonder if they were planning to use two, as it makes sense to with an A380, one for each deck, if the airport is so equipped. In such a case there may have been ground crew moving the (wing) bridge when it hit. Primary responsibility is with that airbridge driver, in those circumstances. And if so, its not tea and biscuits for ground crew. Its foxtrot oscar.
