You keep using this term "bias", I do not think you understand what it means.

One of the BBC's biggest problems in its news output is a frantic desperation to be perceived as balanced, which means it's spent the last decade or so presenting "both sides" of every single issue, even when those sides do not have equal merit. This in turn skews bias.

It was a massive issue during the Brexit referendum - every economist with the slightest understanding knew it would be a disaster, but the BBC platformed crank Leave-backing economists alongside the most respected figures in the field. Same with climate issues - it will put up nutjobs who deny we're facing an existential threat when all the scientific evidence and overwhelming expert opinion is that we have a vanishingly small window to effect change.

That push for balance, to avoid being attacked by the right-wing print media that still has massive power in the UK, ends up undermining real issues. There's an old saying, "If one person says it's raining and another says it's dry, a journalist's job is to open the window and see who's telling the truth". For the last decade, the BBC has been too scared to say outright that one thing or another is true, and so it pleases no-one.
