This is the start of another FUDed up storm in a teacup, there is no-way some idiot would not try to misuse the source code, which is a reason to manage the release. Contrast KDE 4.0 alpha1, there is no way anyone would want that as I dont run Kernel 2.6.x until GKH releases 2.6.x.1, not because I am lazy, I just dont want the hassel. Until manufacturers actually ship Honeycomb devices there is not even moral pressure on Google to release the source and given M$ and FM's efforts I don't blame them being cautious.
If YOU need access for a good reason ask Google, they are very reasonable.
In the mean time I see no gain to helping M$, FM or others talk up another silly set of "patent infringements" with 6 months lead time.
We all know that, with the broken US legal system the existing suits will be in the courts for 10 years long past Android moving on.
