OpenMoko isn't really dead, or at least the kernel isn't: http://git.goldelico.com/?p=letux-kernel.git;a=summary

Netscape was a commercial failure but Mozilla is still around. Similarly Blender only went open-source after a crowdfunding campaign.

CyanogenMod is another interesting example, mostly open source and mostly successful until it started trying to commercialize the code.

I think the community ends up being a big part of it. It's not like every PinePhone shipped is going to result in another developer for the OS, but there is some critical mass point where the software goes from broken to usable and it seems PinePhone might be getting there.

Hol up .. I have a OpenMoko. Never really used. I can install linux with an up to date Kernel on it? Neat. I wonder what I can do with it.

CyanogenMod lives on, in the form of LineageOS.
