They say they are a fork of and are "built on" grapheneOS, which is open source, but don't offer any links to their own repo (that I can find) to see the changes they have made, which to me feels misleading.

open source

no links to repo

Hard no.

Oh boy, this will turn out well....

We start from GrapheneOS, strip out Google and its tracking, lock down the bootloader and USB data paths, and pre-install a vetted set of secure tools. You get a hand-configured secure device without having to be the expert who set it up.

Graphene, by default, already comes stripped of google and automatically locks the bootloader during the install process. This is nothing but FUD.

This company is just using Graphene to boost sales of their preinstalled phones. Prime example: they're selling a 9 Pro XL ($500 phone today) with this fork installed for $1700. FFS.

In case you're curious, I reached out via their contact link and got this response:

Graphene is licensed under the MIT license. I'm not entirely sure withholding the source code is allowed, but I could be wrong. Either way, this company clearly has ulterior motives.

100% ai slop picture here.. 🤮

It's some dudes vibe coded project I think... They probably have 0 clue what it does
