Truth be told, one could contend that an ECN stands to benefit progressively if a customer is fruitful, implying that s/he will remain around longer and they will have the capacity to gather more commission expenses from them. A market producer, then again, being the counterparty to a customer's exchange, profits if the customer loses money, giving a motivator to some shady practices, especially in an unregulated market. The degree to which this happens differs among singular brokers.
