Aside from the project itself: They are eusing a "Polyform License" I haven't encountered that before. So it's not "open source" as many people might expect from GitHub and Polyform licenses seem to inherit the "what exactly is the boundary between non-commercial and commercial" issue as do CC licenses. https://github.com/yjeanrenaud/yj_nearbyglasses/blob/main/LI... https://polyformproject.org/
This is only relevant if the CC is CC-NC, otherwise commercial use is "ok". it's pretty straightforward.
