Not directly but when you use an Android device, you can have a single login to GMail, Youtube, the Android Store, Google Voice, personalised search, adwords etc. Some services are paid. While people who already use those services might use them on Windows Phone or Blackberry, those companies want to push their own services like Bing, BBM, Windows Live/Hotmail, MSN, Skype and so on. When you are talking about 300 million users, the impact of that becomes significant and for every Android user that wants an app, they sign up to Google and they have an access point to everything else.
In the case of voice search, it might show adword links, which people pay Google for so they gain by doing this.
That doesn't explain why they use Apple products in their marketing videos instead of the products of the companies they partner with to deliver Android. If they wanted to destroy Apple, surely they use a Samsung Galaxy S3 or Nexus S. What possible reason do they have to promote the product of a supposed competitor other than that Google doesn't see them as a competitor?
I often hear people criticising Google for what they did with Android but tell me what you'd prefer as an alternative. Apple cannot take 100% of the smartphone market because they aren't on the cheapest tariffs. That leaves a gap in the market. If Google doesn't fill it then who? Microsoft or RIM, neither of which have the slightest interest in supporting Apple or pushing communications and web standards forward nor in making them open for everyone.
I'd like to see Apple getting more credit for what they did and not have legions of Android fans deluded into thinking what they are currently using came entirely from Google and would have existed regardless of Apple but I think the alternative situation is far worse. At this stage, I don't think there's a single thing Google can do to take down the most proftable company in the world. As long as Apple keeps making high quality products, they have nothing to worry about.
Eventually Apple's marketshare will become the minority but that's only starting to happen - Android and iOS will be around 350 million units each and the next iPhone will be the biggest seller ever. There's only 7 billion people in the world and over half can't afford a smartphone:
The entire potential phone market is realistically 2 billion units and Android and iOS already account for 1/3 of this. If they both ship over 30 million units per quarter, the market will be entirely saturated in under 10 years. People will still upgrade but iOS and Android will be the standard that Nokia once was.
Apple won't lose by Google's success and vice versa.
What appears to be free, ...and a gift from heaven of sort, happens to be a multi-pronged channel (Apple, Android and all...) to the ultimate back-room sorting out of human behavior into its fit-for-trade, 'monytizable' components. The very opposite of identity empowerment. Identity swap done under general anesthesia, ...digital DNA going one way(Android to OEMs, platform-agnostic free sophisticated apps to end users), organic DNA(empirical human data) going the other way.
What's wrong with that?
Well..., never has so much omnipotence been stealthily and unsuspectingly delegated to so few already proven untrustworthy megalomaniacs.
Up until two or three years ago, I was service-provider agnostic. Google has made a mortal enemy out of a...then...basically neutral end-user of its digital entrapment. I'm sad to learn that you're into the rationale of an identity swap, ...and attuning you rhetorics to Google's closet, sinister mantra.
