Did Obsidian and Bethesda View Fallout Differently?

As part of their visit to Obsidian Entertainment's offices for their South Park: The Game feature, the folks at Game Informer had a chance to chat with the CEO of the company Feargus Urquhart, and discuss with him on the differences in the company and Bethesda's views of the Fallout universe. The video segment is unfortunately fairly short, clocking at only 1:12 minutes, but still of interest for anyone who follows the Fallout franchise.
