I used to think this, but it's no longer true. BBC radio is pretty good value. CBBC is valuable in having an ad-free service for children. But the rest of terrestrial BBC is .. tired. It's not really changed since the advent of streaming services and youtube, which have eaten its audience from younger ages.

And BBC politics is awful. Question Time is full of planted audience members. BBC journos give softball interviews to their friends in the Conservative party.

Personally I'd split the BBC into National Archive (all the material before 2000) and BBC Ongoing, and make the latter into a normal private company which sells streaming subscriptions. And abolish the absurdity of the TV license and its often oppressive enforcement against the very poor.
