FR deserve the highest credit.
They developed a whole new way of doing airline business and when it reached it's financial peak - they changed their tack. That's what a good company should do.
As to the 'never again' pax, bear in mind that there will always be another generation of 17 yr olds being let off the leash for the first time and those on gap years etc for whom low prices and a bus ride in strange territory will be both part of the appeal and necessary! So, whilst there are those who say 'never again' there are many who say 'Yes Please'.
