No, it doesn't appear to be that at all unless you're making wild assumptions.
We know -
a. From his statement, that NY is unhappy about something BBC related with no real details on that.
b. What the GFL Standard Terms are for artists.
Anything beyond that is speculation / guesswork / assumptions. We have no idea what specifically set NY off. We have no idea whether any concessions (vs the standard terms) were offered to him, and no idea whether any change(s) came from either GFL or the BBC. We have no idea how much leeway GFL have to vary those terms without consulting with the BBC, and no idea how strongly the BBC feel about each aspect of the terms.
I really, really love the BBC coverage every year though.
I think they do a fantastic job both for the many, many people without a tickets as well as people who want to relive the weekend.
