Projects like this tend to be built by people with no interest in marketing, and for a non-profit I think it's fine to keep that particular sort of poisonous corrosion at arm's length.
And I don't mean it as a knee-jerk response, this is open-source, anyone with skills is welcome and if you send a pull request here https://github.com/GrapheneOS/grapheneos.org with the screenshots presented in the way you'd expect them, it might get merged.
- I don’t have a phone that can run it, I’m just curious but without seeing what it looks like it’s hard to become interested
- even if I could install it, there’s basically no chance I would install it because I have no idea what it looks like, because there are no screenshots on the front page
