I am fully aware of the legal background, that's why I try to activate it. The former "information" is better than nothing, but not suffcient anymore (if it has ever been).
Nevertheless I do not understand the checkbox, as I cannot set an option for "Refuse".
I have no clue how this information could be stored without placing a cookie on the client side - maybe on the server side somehow, maybe by adding something (like ?cookies=no) to the URL? Even if such info is forwarded to anyone else with a link it cannot cause any harm.
But actually if I click "okay" without checking the box it appears again on each page, with each reload etc. That is really annoying.
