i'm not entirely sure why the open source community continues to rally to google's defense. google has excelled at deftly maneuvering around license and copyright issues to create something which on its own, arguably does not satisfy the open source ideals from which the original works were derived.
all of these cases will continue to pile up because there is a grey area here that lawyers will exploit for years to come. had google just made sure their codebase was BSD-licensed and their programming language wasn't being sold to oracle, they'd be in the clear...like apple is today and will continue to be. sorry but the apple lawyers got this one right.
these cases won't kill android, but there's a strong possibility that google will have to devote energy walking a tightrope with regards to licensing instead of builing great code.
