What if I said that Pumps could be a non-defensive "building shield"? If you place one in front of a tower, those that have no preference will be distracted by the Pump and attack them instead of the tower (provided there are no defending troops), at least until the Pump is destroyed.

Or it could be the reasoning of the Hog Rider; the Hog Rider knows that the Pump is there for a purpose; to accelerate Elixir gain of the opponent which in turn allows the opponent to create larger attacks, so the Hog Rider might be doing what's best for the whole team.
