As google fi is mostly t-mo + sprint, and t-mo is now mostly t-mo + sprint, it would seem Google Fi's only selling point is it would be nearly impossible to have your phone number social engineered away, because Google support can't be reasoned with?

Fi has other compelling features. The biggest win for me is that it works worldwide for the same $10/gig I pay at home. I went to Cayman and Honduras last year, and it just worked; normally, I have to go buy a local SIM and prepay a few hundred dollars, but with Fi my total monthly bills were still only about $40.
