The FairSearch coalition, whose members include Microsoft, Nokia and Oracle, has filed a complaint with the European Commission against Google and Android, saying that the company is using the OS as a Trojan horse to deceive partners and monopolize the mobile marketplace. Android has become the dominant smartphone operating system when counting units sold, with a market share of 70 percent during the fourth quarter, according to Strategy Analytics. Google is now using that dominance to lock out competition in mobile sector, FairSearch said. The way Google packages apps such Maps and YouTube on Android-based smartphones “disadvantages other providers, and puts Google’s Android in control of consumer data on a majority of smartphones shipped today.”
