It seems to me that a number of points need to be made.
Radio 2 is main stream Uk radio and there is an overall duty to produce a programme of good quality for the majority of a cross section of Radio listeners and not just for died in the wool traditionalists.
Mike Harding is the front man and a damn good job he is doing in keeping the folk flag flying
John Leonard is the producer.His credentials as a folkie person are the best and as a BBC producer even better. John was responsible for the BBC Radio Sheffield Folk programme for many years and has given a step up the ladder for the likes of Tony Capstick, Dave Burland and many other guest presenters such as Jim Boyes and Derek Elliot. Kate Rusby/Katherine Roberts also were helped by John.
If you want to throw stones at anyone try the BBC local folk coverage for example at the lack of folk programmes in the North/East of England.
Local coverage from the Humber through Sth Yorkshire suffered greatly
with the loss of the blanket coverage Henry Ayrton and Brian Swinton provided. Chance is that we folkies were not vocal enough in safe guarding this programme.

What is paramount is the Radio Derby folk programme of Mick Peat and Lester Simpson on Monday evenings who are able due to their time allocation to cater for the more traditional element and provide a good balance for we grass roots knowallsT
This programme can also be heard via the internet World Wide
So if Radio Folk is what you want! ensure that you know all the rules before you start knocking the establishment whose roots are deeper than you think
Good luck to Radio Folk, even if you don't necessarily agree with everything ~ could you do any better? I doubt it?
