Ok, a few things :

1. I dislike her pronunciation of GrapheneOS really emphasizing the "ene" part
2. For anyone not wanting to be stuck buying a Pixel, new or used (still kind of pricey), look into LineageOS /e/, or CalyxOS (though CalyxOS is paused for an interal audit or something)
3. What about other data being sent over your carrier network outside of just Google? You're better off buying a plan for a mobile hotspot so it limits data that IDs you with your IMSI and IMEI info. Carriers otherwise still monetize your data, even though Google isn't getting it.

My next phone will be whatever I want that'll run LineageOS (sure, no "Titan chip") but will run F-Droid store, and only run on a hotspot I'll have with me (for work, goes in my work bag), anywhere else can sit in my car or pocket, etc. It'll help as I use private/FOSS apps, randomized MAC for WiFi, VPN services, etc. Hushed or done 2nd phone nine for WiFi calling, etc

I also have been social media free for over a decade now. No Amazon, no streaming services, and self-host anything I can
