The Google AdWords Philosophy is now posted at [adwords.google.com...]

Here's something encouraging:

It all starts with the users

Google's mission is to deliver the highest-quality online experience to our users – those who search with the expectation of finding highly relevant information. Enhancements we make to AdWords are often a part of this larger effort to deliver increasingly relevant, compelling, and useful content to our users.

By focusing on our users' satisfaction and ensuring their confidence in the ads we deliver, we're able to provide you with an audience that's both highly targeted and highly receptive to your message. By respecting our users, everyone wins.
