What about it? The non-current affairs content is often excellent, especially the BBC4 channel. The further from current affairs, the less the pressure to engage in both-sidesism.

"Both-sidesism" doesn't necessarily result in bias, but it does make the content worse; having leftwing nonsense and rightwing nonsense in the same show will result in an equal weight of complaints from both sides, but that doesn't mean the public has been well-informed.
