The hate for Molyneux is not just due to him over promising. It is due to him continually lying to his supporters and taking their money to build and launch a F2P mobile game that still receives updates even though they haven't bothered to even post an update their steam community in 3 years.
He is still misleadingly selling Godus under "Early Access" on Steam even though he clearly has no plans to continue development and there hasn't been an update in over 3 years.
