Terrible comparison, IMO. Microsoft doesn't sell IIS standalone, it comes bundled with their server licenses. The Windows Server, Exchange Server, SQL Server licenses are what make the money. IIS is just included in all of them. If they tried to charge money for IIS and shipped it for any other OS, it would fail pretty quick as it's not very sys admin friendly and most of it's performance is heavily dependent on Windows threading model.
