Google (NASDAQ:GOOG) is assuming greater control over its open-source Android mobile operating system in a bid to halt ecosystem fragmentation, informing operator and manufacturer partners it must now approve all significant tweaks to the platform.

There are two ways to look at this:

1) It’s good because manufacturers and carriers invariably make a pretty great thing less great (and often crappy).

2) It’s bad because it’s less “open.”

I tend to side with the former argument. While it’s unclear if Google’s new directive would block projects like HTC’s Sense UI (I doubt it, given how well HTC’s phones sell), it may put a stop to some other carrier customizations that do nothing but clamp down the software, install bloatware, and alter the user experience to please a few design-blind executives.
