While the name is elegant pronounced in the original Basque, I suspect the unfavorable comments are from people pronouncing this name how Eu- beginning names are usually pronounced in English, which is with a Y sound. Said that way, Euria would be pronounced like "urea," which is a main chemical substance present in urine. (This is why someone said Euria sounded "rude.") This association in Anglophone countries is... unfortunate.
