Some things I've been thinking about a) Is this about firewalling disappointments and legal problems from Google's core business from the new things that will drive it for the next 20 years? b) Will they spin out Google's Europe operations in to a separate company so EU regulatory actions have minimal impact on the rest of thier business? c) Are there other changes they are worried about to the ad business? Proposals to change the tax status of advertising deductions (US) would hit their bottom line hard, even if it if their ad auctions algorithms continue to behave as shill bids. Will be interesting to see how this changes the main Google business, for better or worse.
