I think he's saying it's not actually going to kill Android or any other Java-based platform (like some people fear), but it might make some people a little more skittish about embracing the platform and it might drive OSS development to a platform whose rightsholder doesn't go around suing people for trying to create their own version.
A change (for the worse) how the dev community perceives a platform is (or will lead to) a significant impact on the platform?
Or is he saying usage in big corps (where devs don't decide the platform, mangers do) won't be affected?
Minor nitpicks aside, decent essay!
