Media Backlash when the Manics Visited Cuba

[Bryter Layter]

What's the deal with the media contempt before, during and after their visit to Cuba?
I went almost completely off the band after the release of KYE (didn't like the album at all, but some songs have since grown on me) only to return to proper fandom with Lifeblood, so I really missed the whole Cuba episode and subsequently wasn't aware that they were given such a hard time by the British press or even some within their fanbase.

Personally, I always assumed the British public's attitude towards Cuba was similar to Canada's in the sense that we don't neccesarily dig the totalitarianism, but on the whole, we generally don't have a huge problem with their politics. Am I wrong in assuming that? Was the major point of contention that they met Castro or was it because they were charging a fee to see the show in a country where the average wage is quite low?

Sorry if this has been brought up before. I'm just interested to know why their visit caused such a stir in Britain.
