While the waiting period has expired in China and in the U.S., both countries have informed Motorola that they have not completed their respective investigation. Last month, the Chinese Ministry of Commerce said that it had started Phase 2 of its investigation of the deal. While there hasn't been much media coverage of any objection to Google buying Motorola Mobility like there was with the never completed $39 billion proposed purchase of T-Mobile by AT&T, there have been consumer groups in Europe writing to European Union to try to get the deal stopped while in the U.S., Consumer Watchdog has also written to the EU to ask them to scrap the merger.
Consumer Watchdog has written several letters accusing Google of being in bed with the U.S. Government. They also have made several videos (see below) criticizing Google's Chairman, Eric Schmidt. Part of their letter to the EU reads, "Allowing the Motorola Mobility deal would provide Google with unprecedented dominance in virtually all aspects of the mobile world – manufacturing, operating systems, search and advertising. It would be a virtually unstoppable juggernaut. We urge the Commission to block the proposed $12.5 billion deal." Despite these objections, Motorola Mobility still expects the deal to close early this year, but does say that factors outside of its control can delay or scrap the deal altogether.
