Hello, I’ve become quite privacy-conscious these days and have a few questions:

1. is an Android smartphone using LineageOS “private” enough? I am aware of all the security problems that having an unlocked bootloader entails, and that GrapheneOS is the golden standard for security alongside all the on-board hardware enterprise security features of a Google Pixel, however I am not on-board with giving hundreds of dollars to Google of all companies for a relatively poor product

I do not believe I have any reason to care about security - I am not currently hiding from any organisation, or any”one”, all I care about is minimization of data collection by companies and governmental institutions, I have seen that LineageOS still pings Google servers for things like eUCC or DNS, is it possible to modify this through a terminal to fully “degoogleify” the system? I would like it so the only time I have anything to do with Google is when I personally & manually use a Google service

2. is it possible to “containerise” a digital identity? meaning to sparingly use social media platforms from companies like Meta on a separate Gmail account separate from my own personal Proton Mail, perhaps on another browser? where I can somehow “detach” the identities, is this a reasonable thing to do?
