I think it's good that Google apologized. First of all, "the ugliest language" is a very bad adjective. I think it is quite wrong to call it ugly for the language in which people express themselves, write poems, and sing songs. A language may be pleasing to our ears, we may love a language, we may be eager to learn a language. These are beautiful things. But we cannot call a language ugly just because it does not appeal to us.
