Google bought Motorola to protect the Android ecosystem from patent litigation. For the purpose, they didn't have much to choose from.
Nobody knows yet what other rules will Google decide to have over Motorola.
Google need Android manufacturers to use their cloud technologies.
Even if Google would give some preferential treatment to Motorola (which I don't believe), they could always offset that by giving manufacturers other compensations.

There's always the possibility that if owning Motorola is seen to be a liability, then Google could just sell it again, but hang on to the patents that it appears were the main target of the acquisition. I don't expect that to happen in practice, but it's not as if Google have painted themselves into a corner they can't get out of if necessary.
