All of these activities will create foundations which Google can control, and which will support the continuous expansion of its plat-form, the element of all this which actually delivers revenues via services, applications, content and advertising.
Nope. It will not. In order to do these, it will leverage its "significant market power" (as defined in Eu competition law) in other areas. Trying to do this is a nearly automatic 10% of Google's worldwide turnover into the Greece rescue benevolent fund combined with regulatory intervention.
This is an essential difference between USA and Eu law:
1. Eu does not require a monopoly to intervene, having a sufficient market share to bend the market conditions is sufficient intervention grounds. Google has that in services, mobile OS, search and advertising - every single area mentioned in this write up.
2. Trying to leverage an area where you have a significant market power to "invade" another one is an automatic intervention. It may not happen today, it may not happen tomorrow, but it is guaranteed to happen and may be backdated by more than a decade for fine purposes if need be.
So yeah, sure, Google can try to strong arm its way into _ANY_ area it likes using existing assets. It is guaranteed to get whacked. Even the astronomical amount of money it has used to sponsor TTIP and friends will not help it here, because it is an _EXISTING_ legislation - so TTIP arbitrage rules do not apply.
It is one of the interesting aspects of Eu market - a player which has reached the "significant market power" criteria in one market is actually disadvantaged in entering new markets or expanding in markets where it is not in a pole position as it cannot leverage most of its existing assets. Compared to that a minor player can cross-bundle and leverage as much as they like - until they reach the "power" criteria in one of them.
