Top end of the scale is 15. It's a linear scale.
- Philip Morris: 15
- Exxon: 13 (see link to #1)
- Goldman Sachs: 12
- Facebook: 12
- For profit health insurance companies: 11
- AT&T and Verizon (tied): 10
- Microsoft: 10
- Average publicly traded company: 8
- Google: 6 (revised up after the Google Buzz fiasco, then down when they showed some wisdom)
- Apple: 5
- CARE International: 1 (They're not a PTC, so this is merely a non-evil reference point)
Update 12/15/09: I added Exxon thanks to a comment and because of the Philip Morris synergy. Exxon's astroturf climate change denialism (see also) campaign puts them in contention for the most evil publicly traded company of the modern era.
Update 1/6/10: Both Google and Facebook moved one notch up the evil scale. Google because of their arrogant, haphazard and uncaring Pages to Sites migration and Facebook because they sold their users out to their often crooked "Apps" vendors. Facebook is now more evil than Microsoft, and Google is tied with Apple.
Update 2/16/10: Google had dropped to '3' after unblocking China, but then leaps to '8' after the Google Buzz fiasco.
