No, both parties get value. Suppose a user would receive 1 utility for donating $1 to some cause in a traditional fashion (e.g., giving the charity money directly). Using this platform and with an OmniMatch of 25%, the user will effectively donate $1.25 for the cost of $1 and accordingly get 0.25 extra utility. The user gets surplus utility no matter what. The platform, on the other hand, needs to be careful in what markets it creates and how it sets OmniMatch, in order to make money.
