Kottonballs Why advertise that we're using a non-standard OS?
People live very different lives. I spend a lot of time on a university campus. Today a student asked me where I got my DuckDuckGo t-shirt. Students are a good potential source of future GrapheneOS developers, so "advertising" to students (for those who are comfortable doing it) may pay off well over time. But people in other circumstances may well not want to advertise.
Kottonballs This OS is worthing paying for which is why I donate yearly.
Thanks!
