I was discussing this cadett thing with a Ryanair captain and he said that he finds it very strange that companies like JET2 or Cityjet does this.
He means that big national carriers like BA or LH are so big that they can say that we only take pilots from these schools etc. But he doesn´t think that companies like JET2 and Cityjet are so important that they can do so. What he means is who are they to say this?
