People do care about privacy if they are given fair choice.
When choices are between
1) FREE (in small print, give up privacy) vs 2) Pay $X (and protect privacy)
FREE overwhelmingly influences the choice.
However, if you find a market where all competitor directly charge comparable prices to consumers for the product and choices are
A) Pay $x and enjoy the product vs B) Pay $x, give up privacy and enjoy the product as well ads
then it'd be interesting if option B) would gain significant traction.
