I thought that I was being clear, but let me do so now... When I said "if you had not resisted the move to Win 10 back when it was released, it would have been free. So having to pay for it to put on an existing computer is your dam fault", I was actually talking about the upgrade being free. Yes, that implies that you had a valid Win 7 license to upgrade, and Yes, that implies that the original is replaced with the new. But the fact is, if you had taken advantage of the offer, the upgrade would have been free. If you want to upgrade now, you get to pay again (meaning that you paid for your original Win 7 license now you get to pay a 2nd time to get a valid Win 10 license). So, YES, the upgrade was free and now it technically isn't anymore (I believe that there are still ways to get around it, but I'm not sure). Once you do obtain a valid license, you then get future upgrades for free (you know, the Feature Updates that they release twice a year [yes, for better or worse - an argument for another time - I personally hate how they are slowly killing off the "Control Panel"]).
My objection is how you choose to define the word, "free".
To me "free", means "without any compensation for goods or services delivered. or rendered".
By allegory: You have a crummy old wallet containing $90,00.
I'm going to give you this brand new wallet containing $100.00.
Now, I just gave you a new wallet and a $100.00... "free"..
That's M$'s definition of "free", and apparently yours as well.
M$ has altered the definitions of, "upgrade" and "update", to suit themselves, and their marketing objectives. They've also begun to define Windows as a "service". This is, "Pandora's box", that perchance may be opened by them at sometime in the future, converting Windows to a subscription model.
You can write this off as a "paranoid fantasy" if you like. In fact, I often deem it as such when mulling it over myself.
The fact remains, Windows is not the most profitable segment of their business
(**). X-Box, and their other physical devices, along with "Office 365", probably turn in higher margins. Windows itself, is simply becoming a delivery vehicle.
(**) In example, I have an 8" tablet which cost me $90.00, and came with Windows 10 installed. It's should be patently obvious, the M$, didn't receive $100.00 for the issuance of said license. It should also be patently obvious that a virtual monopoly such as M$, is going to try and recoup its losses in other segments of their overall business model.
