I believe that to be precise they check for the Today programme, the Radio 4 current-affairs slot where Cabinet ministers go to get monstered.
But yes, the BBC was always the voice of the Establishment (which is fine) but it's definitely been neutered. You can see it in the documentary output very clearly.
You seem to suggest I'm confused about this and I would appreciate if you could explain why.
It really didn't read to me like they wanted to completely invalidate your statement.
