That's certainly part of it, and I mentioned the discount on Office365 in my mock discussion, but I mostly left that out because exactly the same logic would apply to many a small business. When something is free, they're a lot more forgiving of things like time requirements than if it costs a little less. Even if a completely rational economic analysis says that doesn't make sense, they will do it. Also, in various situations, it does make sense.
