Here's the Thing. There's traditional music which is defined by it's history. Then there's the trappings: the attitude, the clothes, the mannerisms. At some point those trappings became so dominant by self-fulfilment and practice, that the mannerisms grew legs of their own so you got historical style acoustic music that's also known as folk.
That music is a direct consequence of the folk stylee and it ill behoves traditionalists to complain about something they contributed to at least in part, by conflating old songs with a wider pop-cultural stance I know as grump, the artsy-crafty-beery folk police thing.

Right, I'm off up the pub for a pint of Bladder's Old Leatherbottle.
