Windows isn't free. Office isn't free. All of their enterprise server software isn't free.

Support and training contracts aren't free, either. I don't know if Microsoft does much of that, but it's another option for revenue with .NET.

Microsoft does not grow food, build houses, create clothes, cars, or protect you from foreign invaders. The basic human needs are not met by MS. The business that claimed that open-source was a cancer is just a marketing company with memetic feedback loops. Plenty of over Operating Systems are out there. Their office product is no longer relevant (vis. a vis. Libre Office, Google Docs, and others). Are you telling me a multi-billion dollar company cannot compete with a startup such as Google? There's a reason why. They do not create. Just marketing.

You have no idea just how wrong you are. Excel has no competitor worthy of even talking about. Libre Office is a mess. Google docs doesn't do everything word can and is in the realm of a toy web app.

Why is Google Docs a toy web app?
