imagine Microsoft started going around to every business running Windows/Exchange, saying, "Hey, we deserve some of your profits. You're using our products to make money, and it's totally unfair that we don't get a cut." That'd be ridiculous,right? Microsoft offered a product, and you bought it according to their terms. If you think they deserve a percentage simply because you use their product to make money, then where does it end? Why can't 3M come after you for a percentage because you use post-its.
Well they did do something analogous to this when they were doing site licensing. I don't know if they still get away with the practice but at one time they charged a per desktop license fee. Not a per installed copy mind you...they quite literally charged per machine on the premises and it did not matter if it was running a MS product or not.
That's not the same as it only references in-business usage. This would be like Microsoft asking for a percentage of quarterly revenue from your company simply because everyone is using Outlook/Exchange justifying it as the email service helped facilitate business.
Or how about the Ford company asking a taxi fleet for a cut of the per-mile rate because the vehicles are all Ford made, ignoring that the vehicles were all purchased paid in full by the company already.
