Jim - not being patronising at all - just an honest opinion from one internet 'folkie' mate to another...

All the great things you do for trad folk are unfortunately partially cancelled out by your negative strictures..
I've witnessed the effect..

For instance some years ago, when that young modern electronica folkie living in France
made an effort to seek out your permission to cover a song in your collection,
and you refused.
If I recall correctly, only after lecturing us/him on why he was not fit enough to record that song...

He would have been intersting new blood for aging & declining mudcat community,
and that was the last time we ever saw him here....
