This is like suggesting that McDonalds' "over xx billion served" mantra is supposed to mean that there are over xx billion customers in their store at any given time.
Except that "served" is past tense and "use" is the simple present. If 37signals had said 3 million have "used" their software, this discussion probably wouldn't have kicked off. Instead, they used the present tense, implying that 3 million people routinely and currently use the software, which is highly unlikely.
