I've seen multiple stories of people buying phones from Fi, the phones never arriving, google refusing a refund, and on a chargeback, their entire google account gets shut down.
I still use 2 Google services, of which neither would crumble me if lost (YouTube, and my old email which now acts as my spam inbox). I have lost accesses before, when I was still partially dependent, and had to give up my privacy to get access again, long enough to get off. It sucks but I do consider myself lucky that I was able to prevent the life crushing consequences that some people have had. Such a terrible company.
