What is your evidence it has caused backlash, or that it hasn't actually had a benefit? The whole article claims the contrary: that it works.

I do agree that some behaviors can be counterproductive, like those pests who blockade busy roads or glue themselves to paintings "for the environment". Not only do these privileged and spoiled punks unjustly impede people from living their lives and destroy culture (they seem to always glue themselves to things that still pass as art, never the banana duct taped to the wall), but they only foment antipathy toward anything environmental, harming legitimate concern, action, and legislation in the process. The social deficits and ineptness of these people is astounding.
