You tried to argue with someone else over this, but the fact that more people played it, being F2P, means that more people can agree that they wouldn't recommend it. Given how Steam ratings work, that makes it the worst rated. There's no arguing how it is. You seem to take an issue with it as if it meant Gabe Newell personally stamped it with a 0/10, which is not how it works.
In Steam, being 4/10 for thousands of people is worse than being 0/10 for a couple people.
