Had a look.

They're offering CalyxOS or GrapheneOS running on a Pixel 6 or 7. The blurb about Titan M2 is generic.

I guess they're offering this 'preloaded' and introducing it in a more attractive way than the 'dry' marketing of the open source projects, so in that sense I approve (although it's a bit funny and I'm kind of envious).

Speaking as a samourai wallet and dojo node runner who also has a Pixel 5 that I flashed myself with GrapheneOS.
