QuoteAfter scrutinizing the nature of Google's interaction with the open source software community on matters relating to Android over the past few years, the fact that they are declining to release source code now doesn't seem like a change in direction. It's the natural evolution of a culture where openness is a marketing gimmick and not a core principle.

Maybe they're looking to re-write some of the code they stole before releasing the evidence.
