@jon The Ordnungsamt would no doubt respond to the Ombudsman that they don't have resources for more enforcement. But depending on where the fines are paid, more enforcement would probably pay for itself. So the Ordnungsamt could also be accused of wasting public money by failing to collect due payments. Also, they are distorting the market and violating the commercial rights of private parking facility operators by competing with publicly funded and illegal roadside parking.
