Another key tenet is the universality of the fee. Everyone pays the same rate regardless of background, so there should be no preference/bias to creating content for a wealthier demographic that may pay a greater proportion of the fee.

The funding is equally shouldered across the population, so the content should be created with equal consideration too. In practice doesn't always go that way, but that was the principle.

The funding isn't controlled by the government but it may aswell be given how the BBC board is selected and their approval of the non-executives and the director of the BBC. The Queen (i.e. Ministers on her behalf) appoints all of them.

Those appointed from outside the BBC tend not to have any background in NGO or non-profits. Bit strange for a not for profit public broadcaster.

It's a very hairy arrangement and I don't think most of the public are aware of it.
