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.
