Earlier quoted context omitted.
Political reasons? Yes, the UK is leaving the EU, they do not WANT to be part of the EU anymore. Letting go of a domain extension is only a small price to pay in comparison. They can't have their cake and eat it too - leave means leave. That's 250.000 domains whose owners and (if applicable) personnel had the option to vote remain. Of course, they can still move to remain in the EU after all.
The terrifying thing is that people with your mindset are actually part of the bureaucracy of the EU. No credible company will keep a .EU domain if they go ahead with this unhinged plan to delete 250000 domains.
The EU is actually quite efficient with its money considering all the things it does. Probably because loads of things are done centrally instead of repeated across 27 countries. This despite the stupid continuous moving between Brussels and Strasbourg.
