while I agree with you I think it is also common for authors of articles on design patterns to talk up the design pattern as something new, and give it a horribly abstract name like 'dependency injection' instead of something common and specific that people otherwise familiar with the pattern can easily map their experience to. In the case of 'dependency injection' which to the best of my knowledge is just 'passing in data to the constructor' this may have been a new concept for the people that came up with it, or it may have been a rebranding effort.
