Probably from that bizarre electric airline who picked the brand name Quantum XYZ, then didn't secure the matching .xyz domain, instead operating off of FlyQuantum.com.
I guess that was a costly lesson., assuming it was them.
There must be a group of tech savvy venture capitalists, or founders, or techies that just love the .xyz extension and can't wait to start a business on one, the way these things sell for. Just uncanny.
