I did mention that part briefly. And I am still a bit confused about the decision as well given some of the subjects that suppressed.
I guess 2010's Google didn't want any trace of a popular gaming store to take over, given that we now know F2P mobile games are 70% of the app store revenue (and I'm sure it's similar to Google). If EA made the supposed Steam of Android and most games chose to focus on the EA store, that's a huge cut into Google revenue, even if most other apps would still be on the play store. So better not to risk it at all.
