I find it crazy that there are people out there who care about ethical repairable tech enough to invest hours and hours into Fairphone, have the know-how to hack away at Linux on mobile and develop hardware support, and nevertheless use Reddit and Twitter as the only channels to communicate this work.
I get that the Fediverse is still pretty niche by most standards, but for FOSS development it seems to be a pretty obvious meeting point.
Edit: It turns out the other FP6 hacker is also making their own non-federated Reddit alternative, which probably explains the absence from the Fediverse. 🙃
