Newb question: what does it really mean when I click “Reject Nonessential Cookies”? Am I really being any more private by rejecting these? Just feels greasy like it’s a workaround for websites to get my information anyway? Should I navigate away from any sites that suggest this cookie configuration?
As others said, configure your browser to store as few cookies as you can tolerate (because some actually useful stuff will break without them) and forget about these banners.
Although I do enjoy the ones that have actual usable toggles for “legitimate interests” - how nice of them, giving me an option to disable even cookies they can legally store with just a notice, and definitely not just hiding non-essential cookies into a vaguely defined category.
So I always go through the list and disable them one by one. It does nothing but waste my time, but I do it out of spite. Oh, and when I feel like really wasting my time, I send a bug report to whatever support email I can find on the site, about how the cookie banner accidentally let me disable essential cookies and should probably be fixed.
