Huh. Wasn't aware. They're the only one in my list I didn't pay for, I think. With wine, eden, puravida, nostrplebs (indirectly paid for with NIP09 verification), and bitcoiner.social, I'm getting a pretty good experience. In all, I've basically paid less than $15 in bitcoin for an app that is consuming most of my screen time, battery life, and mobile data.
