They use every loophole legally available to them (you know what I mean, the button “I agree to sell my soul” being a hundred times bigger than the link to “I’d like to review your data collection and say which analytics service I adhere to”). But I haven’t seen a website where they threaten compulsory personalized ads if you don’t pay. It’s generally “pay or you get cookies”. But I tought those weren’t third party cookies, just in-site ones.
