All I can say is that if my opponent were duplicating our game on an actual board as we played, I wouldn't mind, as long as he was 100% deciding his own moves.
But others might not feel the same way, so using a board might be considered cheating, or at least bending the rules or being deceptive. There's no clear ethical answer here, so you just have to rely on your own conscience I guess.
I'm completely happy with your interpretation. The screen board is a means to transmit your choice of move, right? Seems weird to think that this is insurrectionism.
I submit to you sir! I am not an insurrectionist!
Yes, it's better if we don't give that impression.
