Too many companies say they care about an important issue, sponsor events, and then turn around and fund organizations (or politicians) that actively fight the important issue. This behaviour by corporations is unethical and wrong. One person got so sick of companies claiming to be in favour of issues only to fund campaigns opposing it that he built an app to out the corporations. The Bobbele app allows you to scan a barcode and see what corporations fund behind the scenes, plus any controversies the companies are embroiled in.
A good example is Google since they gave up on doing no evil their controversy list is rather long.
From the creator of the app:
I use the wikipedia dumps that are provided monthly and go through all articles to filter out company and product related ones and all the relevant sections which might be controversial. I do a lot of post processing then to link all the companies based on the parent and owner information so luckily no manual labour and its easy to keep up to date!
