Unless these different Android flavors all have the resources to indefinitely rewrite AOSP and remove all Google code they don't agree with - no, they pretty much have to adopt the changes (see the earlier Chromium example). And if they do somehow manage this after a point all the patching basically becomes a fork, which is exactly what I started the conversation with.
replyI see your point, but it all hinges on when you consider the changes to be a patch set and when a fork. I don't think there is a very clear definition, except I don't think most of these projects would call themselves AOSP forks.
replyAt any rate, this particular Google anti-feature does not require a large patch (or maybe none at all).
