They could have a privacy feature (default on) which blocks or poisons specific endpoints on specific hosts belonging to e.g. Meta, Alphabet, ByteDance.
Apple are in a unique position here to protect users' privacy since they control the browser of so many. It's unfortunate that they also have their own advertising agenda so any steps they take will always be scrutinzed as being anti competitive and simply making their own ads more profitable. But I'd still want Apple to pull the trigger on more drastic measures like these. The last round of privacy isolation should just be the start. I'd love to see apple e.g. block Facbook ads inside the facebook app and refer to privacy concerns and only unblock them if Meta follows all privacy guidelines elsewhere.
Right? If they actually cared about privacy they’d forego revenue for it. Sadly it’s just for marketing.
