Why Does My ListView Look Different?

It seems to me that the following statement, made by an official Motorola representative, purposefully breaks Android's paradigm of developing an app so that it provides a consistent user experience across all devices.

If you like the gray bottom-of-list background on the Motorola Android 2.3.x devices, and you want your application to blend in with the device rather than look the same across devices, then you’re set. You don’t need to do anything.

The simple fix

But if you (or your client, or users) want the ListView background to display at full screen, or your application to look the same across multiple devices, there’s a simple solution.

How can there be a "simple solution" to wanting what I expect to be the default behavior... looking the same across all devices?

I understand that the manufacturer's are "allowed" to do this. But is that really a good thing? I mean, Motorola actually went out of their way to break the consistent user experience and force it on the developer to do some stupid workaround.

I feel like this fragmentation issue is getting just a tad bit ridiculous...
