Problem: website cookie notices
I. Some of us don't particularly want random websites to remember us.
I don't particularly care if that means e.g. not remembering my preferred language. (If I need to, I can always bookmark the English home page). I don't particularly appreciate the modern creeping intrusions on privacy either... But mainly - probably for technical reasons - I just prefer browsing an un-personalized Web.
II. Some of us reject cookies.
Or set them to expire after a short time. Or configure the browser to forget them all when it's closed.
