Important part are not why you buy but what are you buying. Even though anonymity is never perfect, stil it might be less likely to get abused by someone. Our personal data are very important and we should defend them at all cost. Moder companys collect them and use them in various ways, not only targeting, marketing but also enforce they will on our consumer lives. Not to mention that I dont want everyone knows what kind of stocking i am buying and why and for whom. It is my data and i wana do what i want with them and have the most control i can get over them.
