Yeah it's not as if everyone else on site is being paid top dollar. Some are, for sure: various security, structural, power, safety etc stuff can't be got on the cheap (and shouldnt be) but all the artists take a huge paycut, the vast majority of the staff on site are unpaid, etc. No reason the same can't be true for some of the digital services they need to put the fest on. It's a prestige project, after all, and fantastic marketing.
