Perhaps I didn't explain clearly. With F1 hybrid seeds, farmers buying the second generation will lose the yield traits. But Monsanto's Bt crops are not necessarily F1 hybrids - the major beneficial trait is the engineered one, which is stable across generations. So with the Bt crops, they maintain the breeder-farmer relationship with licenses, because the biology doesn't require it anymore.
