Fuckwit is a tad harsh, erm... the men can be very cruel. Poorly advised might be a better way of putting it. Any driver or any firm can charge any amount provided the rider waives his right to have the fare calculated by the taximeter. As suggested, pass the documents referenced on to your legal man.
Obviously apps have brought a lot to the table. As far as stimulating demand goes they have put taxis in riders' pockets and use clever little tricks to predict when they can entice them to use a taxi including capitalizing on the addictive nature of screen based systems. They have also opened up a whole new world of work to drivers. Before we had apps we were tied to one depot with geographical limitations and the men who didn't subscribe to a depot were tied to the county or counties in respect of which they are licensed. Now there are no borders resulting in vastly improved productivity. Of course that costs money, the question must be how much is a fair price to pay. Obviously, improved productivity is beneficial to the environment in reducing dead mileage which is good for the ozone layer and helps reduce traffic congestion, both of which ought to appeal to (local) government and the population in general.
