I like some of the features, but the website doesn't tell me why I should trust them, or directions on how to build the OS from the source code for people who have never done something like that, like me (not that I'd be able to audit it anyway).
With GrapheneOS, enough people have their eyes on it, that I can trust it without reviewing all of the source code and compiling it myself.
After looking what alternative mobile OSs lately, there seem to be a few around. The ones that have appealed to me so far are Ubuntu Touch, Mobian and FuriOS. I see there will be a Ubuntu based version here soon. What I can’t understand though, is why don’t these really clever people work together on fewer solutions with similar end goals? Is it that it’s difficult to manage opinions and decisions? Or that people don’t check the market before developing alternatives? Or something else?
The thing is they the projects are not really that separate.
FuriOS is essentially Droidian for Furi Labs phones. Droidian is Mobian running on the libhybris/halium compatibility layer. Ubuntu touch is one of the older linux on mobile projects also running on libhybris/halium.
These all then contribute back upstream on the various projects that make linux on mobile work.
each one wants to be the person/group controlling the whole ecosystem - you can't easily do that by joining forces with established groups.
