As an intermediary model, the execution of orders is carried out by the liquidity provider through the aggregation engine. Since the counterparties of the transaction are not companies that act as intermediary dealers, they are not interested in the loss of the trading account, and the loss of the customer's trading account is not beneficial to them at all. In the market maker model, the company of the dealer is the counterparty of the transaction, and they decide whether to accept the order of the customer or transfer the order to the liquidity provider. If the dealer's company is accepting the customer's order, their best interest is to make the customer's trading account unprofitable.
