Cookies are not evil per se... but data mining companies made them like that.
I'm administrating an online store and cookies are responsible for the customer's cart, plus their user session / logged in state.
As an admin I adhere to the "golden rule", thus there are no creepy trackers on store. I don't like them and I don't want customers to face the same thing on websites that I manage.
That said, cookies are needed for user session & fraud protection. Instead of nuking cookies we shall kick the trackers out.
