I can't speak of the MI5 accusation but the elite opinion one is comically of the mark. The (economic/political) elite famously hate the Beeb for its "leftie" views (really, it's just being balanced and telling the facts that they object to). The Tories would love an excuse to tear it apart but historically it's been too popular for them to get away with that.
If you had meant intellectual elites then maybe you would have a point but I don't think that's what you were saying.
Then I remember the Jimmy Saville cover-up. Britain's pound shop/ dollar store Epstein.
> senior managers were not told of complaints about Savile because of an "atmosphere of fear" which still exists in the BBC
Written 10 years ago and still true today. It's just that the lies de jour depend on who currently holds political and (to a far grater extent today) cultural power. The elites, in a modern cultural sense, are not necessarily people with traditional money and power (royalty, politicians, famous stars and billionaires). Undoubtedly they have power, but these days that type of power doesn't protect you from the mob. Today, power is wielded by people who claim to have none, yet somehow set the tone on social media (moderation rules), influence rules within universities, influence charities and NGOs, and from there, media outlets. Politicians today are just landing to all. The BBC has is right up there with all the other liars.
