I don't think Jenny was 'blaming' the festival.
But it highlights the fact that there are many things outside a festival organisers control, that can spoil a festival or make it memorable, and influence the decision to go back next year, or try somewhere else.
Chester had a problem this year with lack of pub venues in Kelsall - next year should be better, one pub has reopened, another had a change of heart about folkies.
Another a big factor is the weather - it can flood a camp-site, ruin the displays and outdoor collecting, and for some, spoil the atmosphere, but all the organisers can do is make contingency plans.
