I know this has already been discussed somewhere, but what I meant in saying that "Sauron did not have control over the Three" is that despite wielding the One, he had no effect whatsoever on things done through the use of the Three. Like if Galadriel used Nenya to establish Lothlorien, Sauron could do nothing about it using the One.

As mentioned above, the Three were just as much under the control of the One as the Nine or the Seven. Only, Sauron never got a chance to control them. The main reason that drove Sauron to attack Eregion was that the Elves, contrary to his plan, took off all their Rings. Thus, Sauron had no power over them in the Second Age.
