Exactly! And why is that not being implemented? Because Chrome is top dog and they're earning a lot of money with your data, so WHY would they want to stop that data flow? Everything that would make it easier for you to protect your data would lose them money, so they have no incentive to do that.

Instead, we are stuck with these annoying cookie banners, which are easily and wrongfully blamed on the EU instead of on the website owners and the browser vendors.
