Lack of trust, for the most part. I’ve been screwed over a few too many times for me to rely entirely on someone else. Whether it’s Audible claiming I never bought an audiobook I knew damned good and well I did buy or seeing someone else getting their life made difficult by Google, Apple or Microsoft, or “friends” and family making life difficult, I’ve learned the hard way over the years I can’t rely fully on anything not under my control.
