It's fun to have your own extension, isn't it? then you can host http://hooli.xyz as well, which is good fun too (It's the parody website of the equivalent of Google in the TV show "Silicon Valley", which in itself is a good amount of self-irony).
You're correct, very interesting. In summary, Daniel Negari paid $185k for the .xyz, purchased a few other gTLDs, and Alphabet supposedly only pays $9 per year for its domain. I presume Google is confident in xyz having no security breach and a good disaster recovery procedure ;)
