Since exposing is very underutilized in Netrunner, it isn't very likely that the net damage will ever land. (Unless you are playing against Silhouette: Stealth Operative, but she isn't very popular either.)
Trashing a program for a click and two credits is good value, but it's the runners choice, which severely limits the punch in the mid and late game. Also, if there is a Crypsis or Overmind on the board it is worthless.
At 3 influence, it's not even likely to be splashed, so there is no surprise factor with it being played out of faction. All in all, a very weak trap, although the flavor is fun.
