I genuinely don't think you should have even the ability to give up your privacy, for the same reason we don't allow people to sell themselves into slavery, or give up the right to a fair trial, or give up your freedom of speech, even if it's clearly written out in a ToS that you are giving up those things.
I think there should be a bunch of fundamental rights that all humans have, and there should not be the possibility of selling or give those rights up.
You are also allowed to give up your freedom of speech - it’s called a non disclosure agreement.
If a feminine hygiene company has to show non targeted ads to 50% men, who benefits? They have to advertise more than twice as much, Facebook can't charge as much, and I get weird irrelevant ads that make my experience worse.
Can Facebook know that for instance I am a man, or I live in the US, or that I speak English? What is the line?
Ive never seen a practical model for what "privacy" means in this regard. Of course targeted ads are not new, as advertisments you see in Vogue is different than those in Men's Fitness and different that those in Jet.
So happy to consider the idea that privacy is something that can't be sold no matter the price as long as you have a coherent model of what privacy is
[0] Amusic individuals have diminished or absent emotional responses to music, and describe music as "unpleasant" or as "annoying, noise".
This is how I regard adverts.
So then consider that when you go to other websites, with FB code embedded within them, some of them e-commerce sites, they will be able to retarget those ads, which you already showed at least slight interest in. This is likely a huge difference.
You already showed interest in that gaming mouse, but for whatever reason you decided you would buy it later or not now, maybe forgetting all about it eventually, but then you see that ad to remind you. That's a huge difference.
