I would imagine if Gatwick got 60 to 135 inches of snow every year without fail, it would never close either...
Possibly true. But the today's snow was forecast, and a UK international airport should be able to cope with a mere inch or two of snow.
Same with Hammerfest Airport, chuck grit on the snow, drive up and down with a big heater on the back of a truck, embed the grit in the snow and hey presto. Oslo, on the other hand, same day, utter chaos, and I ended up sleeping in the baggage hall.
Here, a mere dusting, maybe half an inch, but still cold
