Do you also think the engine that comes with your car is free because the manufacturer doesn’t sell it as a separate item and it’s not listed on the receipt?
If including it with a paid product has a cost for the manufacturer, then you did pay for it as a part of the price of the product which you did pay for.

I don’t see how cars and engines have anything to do with the fact that macOS is free.
And, yeah, if it’s not listed on a receipt as something I paid for, you can’t argue that I paid for it. Or that anyone did. That’s absurd.

That’s a guess, not evidence of your claim.
