The Intel and Google keynote speech closed out with a video and an announcement. Each Chrome OS device that they mentioned will be among the first to use Haswell and Bay Trail processors manufactured with conflict-free minerals. They are not abandoning the Democratic Republic of the Congo, rather they seem to be forcing their suppliers to adhere to human rights standards if they want to do business with Intel.
This initiative has apparently led to the creation of the "Conflict-Free Smelter Program" which is run by the Conflict-Free Sourcing Initiative. This industry body includes several other companies, such as AMD, Apple, Foxconn, IBM, Microsoft, NVIDIA, Pegatron, Qualcomm, every laptop manufacturer that I could think of, and over 150 others.
Intel has been discussing this for a little while, and taking positive steps toward this goal along the way. There really is not that many other ways to say it: reducing the suffering in the world is a great goal.
