Yes, that's exactly what it is. Look at the github and look at his commits. Even the markdown on the main github page is almost identical, including grammatical errors, with only a few minor changes and instances of the text "Dynamic" replaced with "Credits". You are attempting to reframe the issue by asking me why a developer shouldn't receive a payout. The issue is that he is not a developer in this context--copy-pasting does not make you a developer. At most, he is a marketer.
