That would require power sockets to not be a monumentally scarce resource inside an airport. Nobody is going to look for the TV rolled between a row of seats (that cause a dozen more people to have to stand or sit on the floor), facing a completely useless direction, to get flight updates. The airport isn't going to drag extension cords across the entire lounge without risking breaking somebody's neck. They'll stare at the blank screens and wonder what's happening. A whiteboard in front of those screens, and other hot-spots, is far more considerate of how people behave inside a departure lounge. Low-tech solutions to high-tech problems can be quite beautiful when executed well. It's a sign of good contingency planning because they anticipated no network availability, rather than betting on network redundancy. I hope the few people who missed their flights were compensated in some way (refunds, seats on the next available flight...).
