If you click disagree, the site just doesn’t work at all. Instead, gadgethacks.com shows you this.
You know, normal sites make you accept the bare minimum that is required for the site to function, and give you an option to accept or reject all the tracking cancer and advertising plague.
Browsers should start enabling deleting every data from any website other than explicitly allowed ones by default.
I've been using CAD (Cookie-AutoDelete) to do exactly that:

Edit: I'm well aware that FireFox/Chrome support this natively, but with this I can share my exclusion rules between browsers and devices, albeit with manual import/exports.
On my iPhone, I use Firefox Focus as my default browser. It deletes all cookies after every session!
Firefox and Chromium do support what this extension does natively.
White listing cookies is the way to go. Everything else just gets deleted after a few seconds.
Sadly this doesn't stop fingerprinting, though it does make it a bit more difficult.
You can do that for sure in firefox, but it will break some sites, especially any that needs some kind of login or settings.
