Do people actually use Google Play Services? They have achievements and leaderboards etc. The thing that worries me is that it's connected with Google Plus, which is, to say it politely, not Google's biggest success.
Google has somewhat on a monopoly on search, but basically bc they are just so good at what they do! Bing's Search goal at the moment is to be 90% as good as Google (I heard this from someone at Microsoft)...
Also, the EU breaking up Google thing is not going to happen. It's a symbolic action...
