I used to work hosting Focus Groups, we would pay cash, and top dollar for even small chunks of specific data sets on demographics that would age very quickly. Since people’s habits change, different trends, feedback, etc. Hence the need of constant campaigns. Today, people give a lot of this data away, for free, in a constant data stream, for months if not years on end for cents or even a couple of bucks a month. Via constant tracking and profiling. It’s crazy how privacy illiterate people are.

Not bothered by the loss. Like others have stated, it can be used to track/profile you, but far more importantly, it was a non-legally binding “pretty please, do not track me, okay?” Request. Based on literally how honestly the server was setup or if the site admins felt like respecting it. 0% guarantees.

I have not been bothering to enable this for close to a decade in all my machines and on those I support.

Always found it weird how it was so pushed in tons of privacy guides or in privacy tips. It’s as if they were just parroting each other without actually thinking why it would or not work at all.
