Well, the BBC is unlike any other news organization, culturally - it is more like a branch of the Civil Service. If you showed up for an interview there as a tech journalist and you actually knew the difference between say Java and C++ because you'd used them both, then you're "just not our sort old chap". But show up wearing the right old school tie, conjugate a few Latin verbs, and spend the interview reminiscing about the good old days punting at Oxford and you're in. So the whole place is stuffed with people who fundamentally can't evaluate whatever they're told by any outsider - not even which outsiders are really experts or not.
