Lou’s idea was just for a server to remember the last state of a browser’s interaction with it. But that one move—a server putting a cookie inside every visiting browser—crossed a privacy threshold: a personal boundary that should have been clear from the start but was not.
Once that boundary was crossed, and the number and variety of cookies increased, a snowball started rolling, and whatever chance we had to protect our privacy behind that boundary, was lost.
The Doctor is incensed.
At this stage of the Web’s moral devolution, it is nearly impossible to think outside the cookie-based fecosystem.
