One interesting part of the news coverage is that there are 600k customers involved, and only 150k of them are UK holidaymakers. Notice the lack of coverage of the other 450k?
An additional factor may be the insurance situation: Some countries require travel organizers to set up insurance for these cases, ensuring that customers can still get back. I'm not 100% sure on this, but I think the UK doesn't have such requirements, which would worsen the situation for them in particular.
if you read a Swedish newspapers they'll talk about the Swedish customers, read a German newspaper and they'll talk about the German customers and so on.
