The US Department of Justice is currently pursuing two anti-monopoly cases against Google - one over search and another over advertising technology. The department has laid out potential remedies in the search case, including making Google divest parts of its business such as the Chrome Web browser and ending agreements that make it the default search engine on devices like Apple's iPhone.
Eh I don’t see that happening, the sheer amount of data Google has on the US population is probably quite useful to the admin, for, uh, reasons.
