This argument is getting tiresome.

Spells do what they say they do, and nothing else. If Hex said "this bonus action requires Verbal and Somatic components", it would require Verbal and Somatic components. It doesn't say that, so the bonus action doesn't require components.

Components are a function of casting a spell. When you take a bonus action to move the hex after casting it, you aren't taking the Cast a Spell action. Nobody is claiming that Haste's extra action requires components just because it's an action granted by a spell.
