I don't think that's the reason why. I think they just wanted to capture the same feel that the classic games had and go back to Sonic's roots, if they were just trying to cash in, they wouldn't have bothered making it 2D and if they were trying to shut up "classic fan brats" they wouldn't have given Sonic green eyes and a Homing Attack.
