Back because we never left. The earliest concepts of opsec delineated user's created object history as the domain and responsibility of the local administrators. Calling it as a user "your" data is pretty much a joke. The same data exists on any number of proxies, routers, subdomains,...which they front-end while constantly creating new scripting languages just to facilitate "your" data being traded between the mirrors. So yea, for the most part refusing cookies actually has less of a positive impact than deleting your history before killing your browser session. Further, service providers own, market those mirror platforms and the sessions they spawn end to end by corporate privilege which were created to mock the entire idea of "your" data "your" session.
