Eh, "git" is an unpleasant or contemptible person. "mercurial" is subject to sudden or unpredictable changes of mood or mind. Neither of them ran into any issues due to their names. I think it's really only a problem if a word is offensive/inappropriate enough that people would hesitate to say it in a work conference room. For example, the GNU Image Manipulation Program is something I would hesitate to name depending on how senior the leadership is in the room.
The world of screenshot utilities in Linux also has some weird names, with "scrot" being widely used until it was surpassed by "maim" and "slop" on X and "grim" on wayland.
