I hear you, and agree that when he says "I'm an engineer", we have a certain set of laws that apply to that speech.
I'm saying there is another aspect which is the the crux of the reply-to-top-level comment to which I objected: that Final Report is saying "doing [math and stuff] on [public things] is engineering, and you did [math and stuff], so you're doing engineering without a license". I don't think my "the Final Report is saying..." is unfair: check the Final Report sections 8,9, and 10.
I bet there are a lot of confounding issues in this particular case, but, very narrowly, what I'm saying is that using publicly-available data and speaking (without saying "I'm an engineer") of applications of "special knowledge of the mathematical, physical, and engineering sciences" cannot be illegal or fine-able, yet this is pretty literally what sentence three of section 13 (Final Order, Page 6) says is happening.
