The whole agenda of the guy writing this is to move open source projects to being no longer open source, because he doesn't like what that entails (as it also means "amazon enjoys the same freedoms as everyone else"). But they like to confuse it as much as they can.
This would be much less of an issue if these people were upfront: "We don't like Open Source, so we try something else". But they don't want to do that because they know Open Source has a good reputation, so they try confusion and deception.
