The FA is simply announcing that an airline has started service with some ARJ21's, nothing to do with C919. The ARJ21 has been in use in other airlines since 2016. I'm certain that China would have done something like these jets regardless of whether other manufacturers had declined, or if they helped, or whatever. Just as the Soviets/Russians have been making jets and just as in that case it said nothing about Boeing or Airbus.
