I was always under the impression that the number of followers, and the quality of the collective devotion, directly influenced the gods' power and influence in the FR.

Your impression is correct when it comes a god’s power; a deity is greater, lesser, or otherwise in direct relationship to the strength and quality of their worship.
Their influence among mortals and their fellow deities, however, is partly related to their. 2)
…power, but is determined more by how they wield that power: their deeds and actions.
If a mortal comes to mistrust a deity, and worships them out of fear or to keep their displeasure at bay, that worship is of 'lower quality' than eager 'love and trust' worship.#Realmslore
