if I may know why domain use XYz ?
what is the problem with that? .XYZ is TLD, same as .com, .net. Google's parent company is starting to use abc.xyz.
I have no idea why people are so prejudiced against .xyz domains. Did some scammy sites used this domain frequently or something in the past?
As you said this domain is no different than any other already established domain. It is just new addition to the domain pool aimed to expand number of available domains.
