I kind of see where the "outrage" might come from in the lead as apparently they promised that the shoes were going to be recycled. However, the mantra is "reduce reuse recycle". Clearly it is better in the save the planet sense that perfectly good shoes were reused rather than destroyed for playground padding. I'm a liberal in general but this kind of false outrage makes us look foolish.
You're not looking deep enough. The outrage should be that companies imply playground padding (maybe what? 100 tons/year at most) is somehow a reasonable approach to solving any waste problem. THEN they have the gall to not even do that.
The valid outrage is how easy it is for companies to manipulate people.
