Wikipedia is a service puts up a huge banner every year asking you to please give them money if you don't want them to be forced to show advertisements, implicitly making you the product.
I say, the lengths people go to justify a trite thought-terminating cliché don't fail to astonish me.
If the mere possibility than a service you use might in the future have ads is sufficient to justify the phrase "you are the product", then I don't see how anything can be an exception to that. After all, the next release of Tor might have ads! Who knows?
