It is transparently using the enforcement in a predatory way. Their goal clearly isn't to keep the parking enforced or they would have done it from the start or at least after move in times. That is what is highly unethical - they deliberately let the /problem start/ for profit. They aren't the law either any more than Jimmy's Pizza place is when the call to tow a car that was abandoned for a week.
