I think an important thing to note is that the ban on palestinian flags or mentioning palestine in any capacity this year in eurovision, wasn't the decision of EBU but SVT (the swedish broadcasters). However, EBU has clearly supported and enforced this ban.
That being said, it's disgusting and appaling that SVT would ask eric saade, a half-palestinian man, to perform at eurovision, and then trash him and make official statements berating him for wearing a palestinian garment while performing, because he "made it political".
The reason why eurovision exists is inherently political. Half of the most successful eurovision songs are political. This whole thing is nothing short of a farce and absolutely disgusting.
