Rings of Power talk!

To me, it makes more sense that the Three immediately became powerless upon the loss of the One.
They were "tied" to it after all; there was no delineation made between the influence of the One upon the Three, and that it exerted upon the wearers of the Nine and the Seven. With the One, Sauron could know and govern the thoughts of all of them.
When the One was destroyed, immediate effects were observed. Sauron's spirit was irreparably maimed, Barad-dûr, made with the One, collapsed, and the Nazgûl fell from the sky in ruin. Since those events were not gradual, why would the Three's fading be any different?
