I understand why people are concerned with the BBC’s stance. John Simpson provides a simple explanation in the link below.
I believe the sentence in which he says “The key point is that we don't say it in our voice. Our business is to present our audiences with the facts, and let them make up their own minds.”
It is interesting to read what he says, and it indicates that the BBC have always had this view, with perhaps many of us not realising it.
