Is it me...or anyone notice the similarities? Nighwing vs. WW Logo?

Coincidence or DC Plot?

Having a motiff that resembles a bird stretching its wings is fairly common and similarities are to be expected... otherwise you could say Nightwing's symbol is partially based on Raven's hood or soul-self.
