I just looked up DuPont in wikipedia. There is a very long article about the wonderful things DuPont has done/made, along with a few minor negatives. Here's one:Tax avoidance and lobbying
In December 2011, the non-partisan organization Public Campaign criticized DuPont for spending $13.75 million on lobbying and not paying any taxes during 2008–2010, instead getting $72 million in tax rebates, despite making a profit of $2.1 billion, and increasing executive pay by 188% to $27.4 million in 2010 for its top 5 executives.
Imprelis is way at the bottom of the article and gets about 1 1/4 line.
Maybe one of us could contribute to the article???
