It reminds me of calling 'slippery slope' on an argument. Slippery slope arguments are sometimes fallacious, and sometimes very pertinent. You actually have to use reason to distinguish the two scenarios, not just use pattern recognition to try to spot a match to a list of fallacies. Lots of people using 'what about' are doing so to try to make reasonable comparisons between two cases. Lots of people do it to avoid blame or confuse the argument. You have to actually read to figure out which it is.
