We dumbly agree, out of convenience or some notion that if we wanted to read the paper edition we’d have to pay for it, but one can shell out cash for the paper, pick it up in a waiting room, read a friend’s copy, etc.

If you must subscribe, use a dedicated browser & multiple measures to confound tracking.
