"The name was coined by Charles Parker"
Quite true - the group were doing a benefit concert for the Co-op and they needed a name in a hurry for the publicity - Charles pulled CG out of his head on the spot. Vitually all members later agreed that it was a rotten name that in no way described the group's work.
"Ewan seemed to assume that if they weren't doing it his way, they were doing it wrongly!"
Not the way he workeed or thought; it was an internal way of working for the group, not aimed at what was happening elsewhere - suggest you read (above) what Peggy had to say about the way Ewan worked and thought - and contradict her if you don't believe her.
It is true that standards in the revival were higher in the sixties than they are now, but I got thoughroughly sick of Alex Campbell and his clones telling audiences that their out-of-tune guitars were "near enough for folk song" - eventually the slogan caught on IMO, so much so that you can now read arguments on this forum that seeking to raise standards is detrimental to the club scene as they putt the lesser-talented off.
