Isn't the prices of using Google's play services for "free" by manufacturers that you must include so many of Google's Apps? I mean surely they can expect Google to provide it services without a cost or catch.
If manufacturers don't want to do it then they could still use Android san the play services like a lot of Chinese manufacturers are doing.
I find these anti trust investigations against Google that are based on the fact that manufacturers have to bundle Google's App ridiculous.
