Your sentence is like saying that without Internet Explorer, we would still be paying for internet browsers. It's praising Microsoft for what it did and mysteriously assuming that in absence of it, no one else would bring the cost of browsers down.
This is my nitpick with "what if X didn't exist" scenarios: people imply that nothing would fill the vacuum.
Another example I just made up: "If Linux didn't exist, we wouldn't have a free, open source OS". I'm pretty sure FreeBSD or something like that would grow like Linux instead. Not saying it would be better or worse, because, frankly, I don't know.
