There are two different issues you're trying to discuss here, and it's getting muddled.
[1] The degree of Motorola's access/influence and the degree of the partners' (HTC/LG/Samsung/Etc) access/influence.
We don't know what will happen, but it's likely that the partners will have the same access and influence to Google/Android that they always did. Google is going to "run Motorola as a separate business".
[2] The non-partners that don't license android still won't have any access/influence.
The fact that non-partners won't gain more access/influence to Google/Android because of the acquisition is a non-story. Also a non-story: pigs wont fly as a result of this acquisition.
