"Bought in" is not the same as "outsourced". A programme made by an independent production company is (theoretically) subject to the same editorial process as one made inhouse. This means that the producer, although not a BBC employee, is still bound by guidelines which state (roughly) "if in doubt about whether to transmit, refer up". However, as has been examined in detail many miles up the thread, this process broke down disastrously. Didn't I say this earlier? At least twice?
