Yes. And it is still just spam which you can ignore.

Graphene in the title refers probably to GrapheneOS, is that right? Note that this Android mod does not allow you to do real things with your "phone" (which is actually just a small computer). Yes, most of the Android mods (Samsung, Xiaomi, …) are not any better, but on such phones one is at least able to install a custom Recovery (preferably TWRP) which then lets the owner of the device to install a vanilla Android (LineageOS), optionally with Google Apps and Magisk.

Installing the latter two to an Android phone leads to a device that can run any app from the Google Play store but still letting you as the owner use superpowers and learn. For example by connecting over USB from your computer using ADB.

GrapheneOS wouldn't work if the tech used by Google in Android itself was broken. And because it is not broken, but actually works great, one can install latest Revolut (or any other root-checking app) and use it on a rooted phone by adding it to the DenyList on Magisk.

IMHO making more consumers rather than teaching principles is not the way to go. Android is Linux. Everyone is free to learn.

Like there is a clear thread of history regarding Bitcoin, which leads to understanding the "only" part, the same way can be used to go deeper into history of computers and learn about Linux, UNIX (KISS), birds' nest (architecture) and so on.

All the best!
