The PoMo 0 down scheme has some strict income conditions, so it's not totally crazy. In my view people get "help" on downpayments all the time from family or whatnot, that the developer is "giving" them their DP through a discount isn't too far off status quo.
Full disclosure: my support of this scheme is based on a chance of future entertainment if tshtf. Hate away.
There is no shame in overpaying
