Doesn't mention the words Profit or Value, which is either bad business practice (I doubt it) or a touch of being disingenuous. Some of that revenue goes into profit as you note, even if that profit is then reinvested. And fee structures should never change only because costs have change, which they indicate may be the case. If you start delivering more (or less) value, it's fair to increase (or decrease) your price / revenue share. Focus on value, not on costs, and you will build a much more profitable business.
