The EU is investigating Google (GOOG +0.3%) over claims it violated antitrust laws by giving Android away for free and imposing exclusivity deals for the bundling of Google apps/services (Google Play, Gmail, Maps, YouTube, etc.), the FT reports. The investigation follows a formal complaint launched in April by Microsoft, Nokia, Oracle, and others. Apps/services bundling is pivotal to Google's Android monetization strategy, which has begun paying off nicely. Two big questions: 1) Can OEMs can afford not to pre-install Google's apps even if they're free to do so, given their popularity? 2) If OEMs keep pre-installing them but gain more leverage, will that lead to higher traffic acquisition costs?
