Guest - there are already reports of cases in Whitby. Also, Whitby is a tourist resort. As soon as restrictions are lifted, thousands of (non-folkie) people will descend upon the town within weeks. And Whitby's economy needs this - bills will still need paying, mortgages kept, food put on plates. On an annual visitor basis, folkies are a drop in the North Sea in Whitby. There may be a small risk of the odd ill-informed social media blowhard blaming folkies should there be a spike in cases there, but given the numbers of tourists that will be in Whitby (should restrictions be lifted enough for people to still visit in late August) it will be ludicrous for anyone to blame a particular sub-group of those tourists.

It should also be added that 'folk week' won't be arriving. Just a percentage, probably a fairly small one, of people with existing bookings, many of whom will be indistinguishable from your regular tourist.
