The reason android exists was to allow OEMs to compete with Apple.

Google could shut it down and only publish their own phones, but they don't have the chops to become a premier customer goods maker. The field would be free for Apple until Samsung catches up. In the end Google lose negotiation power in getting their search engine, browser and services on Apple's and Samsung phones.

Basically they would be the main loser in the move.
