The copy on the Adobe site is written for a target audience. Those folks ask: "Yeah, but do customers of my clients have installed Flash?", "Uh, they proposed a solution working with Flash, can we do that?" or "Can we use Flash?". And the answer is clear: Yes, you can! Everyone who doesn't live on the other side of the moon uses Flash!

Note to my fellow programmers: normal people read numbers like words. Depending on the context, a number represents a word to them like "Totally!" or "You must!" or "Everyone!" or "Just Now!" and so on. I know, it's irrational, but that's why the advertisers use those numbers. (Use humor in life, it's better that way :-))
