On one hand, you can say that imitation is the most sincere form of flattery.

On the other hand, you can also argue that the dragonfly posted their complete machine breakdown right on their website for all the world to see. If you wanted to, you could count exactly how many parts it took to make each component.

Unless they posted the wrong image, it's almost as if they said, "Ok world! Here it is on a silver platter! Want to see what our machine is made of? You don't even have to take it apart! We'll take it apart and show you how it's put together!!!"
