the OpenBSD of Communism :)

I imagine building on existing AOSP project like GrapheneOS or LineageOS would be the easiest path forward. There is already a decent ecosystem of open source apps available. You’d still need to figure out what to do with proprietary apps like Slack that regular people might need for day to day use.

Ultimately, the problem lies in lack of a hardware vendor willing to take make open phones that are geared towards running a custom OS on without having to jailbreak them. I really think the only way this can happen is if there was a vendor that focuses on providing a full stack open source system for mobile. Maybe a company like Liberux or even Framework will succeed at doing something like that at some point.

Liberux is using waydroid to add compatibility from what I’ve seen, so that may be the way forward where you have a base Linux system, and then a layer for running Android apps on top of it.
