I genuinely laughed out loud at this. I keep hearing from Kicad users that
they each create all of their own parts libraries from scratch, including
footprints, because they don’t trust anyone else’s. This seems very
strange. What happened to that collaborative open-source vibe?
Very Very good point and a genuine LOL
