Dutch broadcast company AVROTROS has announced that the Netherlands will boycott the 2026 edition of the Eurovision Song Contest if Israel is allowed to compete. The Netherlands is the fifth country to announce a planned boycott of the event, which is scheduled to be held in Vienna.
It’s because they’re part of the EBU (not sure why though, the E here also stands for European). I think that’s the actual qualification for entry.
The E in EBC is basically as relevant as the E in European Article Number (EAN) which are used globally.
