Google wants to strengthen its control over Android

According to a Bloomberg Businessweek report, Google is planning to get more control about it's own mobile OS Android. Bloomberg got that information from a dozen executives from key companies of the Android ecosystem. 

Google will exclude companies from their early-access programme, if they deny to have Google take a look on their Android modifications before the device's public release.
This way, Google gains control over the additions the companies create for Android, like HTC's Sense UI, Samsung's TouchWiz and more.
In case a manufacturer denies to let Google have the final word, the manufacturer will be excluded from the early-access programme. 
In a market, where it's required to be ahead of the competition to get many sales, this is definetily something a manufacturer will not want.
Ahead of the competition does not only mean selling more powerful hardware, but more advanced and recent software too.
Google usually gives the biggest manufacturers early access to the source code of their upcoming Android version and releases the source code publicly a few weeks later. There's one exception right now, the public release of the source code for Android 3.0 was delayed for probably a few months.

So, all in all, losing early access to the source code means less sales and thus less revenue, which is definitely not being wanted by companies.

I'm two-minded about this action from Google. It may lead to better update policies, but it makes Android less open.
What do you think about this? Will Android profit from this change or take damage?
