I’d like to see a cookie notice that just says “it’s your browser, figure out how to get it to handle cookies however you want. If you accept cookies we’re gonna use them and you can safely assume we’ll use them for anything and everything they might be useful for. European regulators can eat a bag of dicks.”
Most are just going to laugh at you and be as unhelpful as possible if you come at them like that. You’re just giving them an excuse to stick to the script and tell you to pound sand. If you let them know it’s not personal but you’re angry at the company and keep your approach professional they’re much more likely to think outside the box, bend the rules, or escalate your issue to get things taken care of.
