The European Union has moved from investigating Google to charging them for supposedly violating anti-trust regulations. This charge is in reference to the way Google has bundled apps with Android, and for the aggressive contracts with Android OEMs which forced them to do so.
Basically, the EU contends that Google’s contracts force Android OEMs to bundle Google’s Apps, like Chrome and Google Search by creating a host of requirements in order to use and license these apps. The EU believes this hurts competition by taking away choices from the OEMs to bundle apps from other developers besides Google.
The EU’s other main problem is that they believe Google made it nearly impossible for any potential rivals to design a competing search engine, app store, or browser for Android. They claim Google did this by requiring the Play Store installed in order for Chrome or Google Search to be installed.
