This is principally a German political and business problem
There's an excellent Economist article - http://www.economist.com/news/leaders/21615602-germanys-opposition-american-technology-firms-short-sighted-and-self-defeating-googlephobia
In summary, it says that the issue is that German companies have been caught on the hop and don't have any genuine contenders in web businesses and are now looking to bury Google and other US tech companies.
And to the poster who tried to tie the Microsoft and Google cases together as if one wasn't significantly worse than the other - for shame. Microsoft went out and destroyed competitors. Google's "crimes" are minor in comparison - but should still be investigated.
This case is about politics pure-and-simple - mostly German - but there are plenty of other shameless ambulance chasers from the rest of the EU.
