@GrapheneOS @domi @elly @mei To be clear I don't think your project is non-viable or a dead end, nor do I think you're not doing any valuable work - quite the opposite!
I like what y'all do on the technical side of things, I know some people who use GrapheneOS as a daily driver and are very happy with it. I personally don't use it because it doesn't support my current phone (Fairphone 5) and I am very reluctant to buying a Google Pixel, but you're still doing nice work and it's great that this is another available option that can be used.
