I really feel like there is bad faith on both sides and I don't see Felipe thinking in Junio's shoes. It's the job of maintainer to make sure to bring out collective progress and empowerment and this requires some amount of resolve and authority.
If I were him I would do what's best for the project, not what's best for my ego. If I were wrong about a patch, I would simply admit I was wrong, and apply the patch. That's what every maintainer should do.
There's a difference between using authority in a way that moves the project forward and *abusing* authority to protect one's ego.
Junio does the latter.
