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.
As soon as we attach a subscription to an online edition, all that happens is they get more data on us (as we are les inclined to delete their tracking cookies) whilst handing over solid confirmation that we are who they suspected we probably are.
If you must subscribe, use a dedicated browser & multiple measures to confound tracking.
