I agree, Graphene is not for everyone, and what you wrote is a perfectly fine opinion when it comes to privacy- and security-focused daily driver OS’s for smartphones. If you’re a protester or a journalist though, it’s all or nothing. There are no alternatives, no compromises that can be made. If you use a smartphone you are at risk, even if it’s a Pixel with GrapheneOS.
Graphene has decided to instead frame everything that isn’t a Pixel running Graphene as universally bad.
They did say on several occasions that they would support other phones if they weren’t locked down (Samsung) and commended the security of upcoming Mediatek and Qualcomm chips.
Calyx is not as degoogled as it claims to be (at least it wasn’t 2 years ago, see below). I know this is a bold claim, but the only ROM comparable with Graphene was DivestOS, which was a one human project and was dicontinued last year. And even Divest had the problem where updates were delayed by a few days or weeks.
Obligatory eylenburg link, and there’s this blogpost I like to link to. It’s written in German, but I’m sure it’s a good read if you put it through a translator.
The conclusion of the CalyxOS analysis in English:
Take this with a grain of salt since it’s been two years since this blogpost was published.
Here I deleted a whole paragraph in which I sounded like a Graphene elitist haha. I would say using CalyxOS is a lot better than stock Android or Lineage. Please don’t choose your OS based on vibes. If you need any of the features Graphene offers that others don’t, please use it (edit: like the protester mentioned in the article). If you don’t, don’t.
