Well, many Brits don't like anything about "Europe" to begin with, they actually often use the word as if their island was not part of the continent at all, so any "Euro" topic is an opportunity for some of them to rant endlessly how everything European is awful and anti-British.
Beyond that, i think a power struggle has started between the EBU and the Big 4.
On one side, it seems that the EBU wants to get rid of the special status of the Big 4 (direct qualification) while still making them pay huge contributions. On the other side, it seems that the Big 4 want to reduce their contributions (because Eurovision ratings have been dropping, because there are more countries that can provide, and because the new 'geography' of the contest makes it very difficult for the Big 4 to obtain good results) while keeping their special status.
As often, this should end up with a compromise, the Big 4 losing their special status in exchange of a significant reduction of their contributions.
