Once you have done this outing and shaming, what do you expect to do? Burn the engineer or contracting agency at the center of the town hall? Have a fifties style whisper campaign where you refuse to go to their cocktail party?

Apart from the fact that it vaguely sounds discriminatory, I don't see what you could achieve on a practical level.

What happens when the people you're trying to shame simply do not care about your opinion, or the opinions of anyone else?

Assuming sane people would respond to this criticism by leaving, what would be left with? As with any institution, perhaps it is better to have sane people working there, trying to change it from the inside.
