Minecraft wiki entry for Nether_Gold_Ore, associated text: In 2017, Jeb showed interest in a suggestion regarding Nether gold ore that was posted on Reddit.[1]
This comment also suggested that nearby zombie pigmen, the mob now currently known as zombified piglins, should become angry at the player when they mine Nether gold ore. Jeb also showed interest in this aspect of the suggestion, and this may have been the inspiration for piglins becoming angry when gold of any type is mined near them.
