I try to stay away from Nestle because I fit the left wing stereotype so well that its embarrassing.
and that one time their CEO said that water being a public right an "extreme" opinion, and that it should be privatised: http://themindunleashed.org/2014/05/nestle-ceo-water-human-right-privatized-2.html It's not as bad as it sounds (he caveats is later), but It's a pretty ugly position. http://www.nestle.com/aboutus/ask-nestle/answers/nestle-chairman-peter-brabeck-letmathe-believes-water-is-a-human-right
That and other corporate sins. They are a company that repeatedly does offensive things. The latest is repeated statements by the CEO that all water should be privately held and that it's immoral if water isn't sold at a profit. There are more than enough substitutes for low end commodity chocolate why give this company your money.
