Don't like cookies? No one is forcing you to visit a particular website.
I also feel like tech companies could adopt an open standard for cookie acceptance preferencesin web browsers, but they're afraid to lest they be forced to deal with even more regulation later.
to decide whether to track your users? through third parties? for advertising purposes?
Why? Why do you get to decide and not the users? I'd rather you didn't!
It really honestly does surprise me the amount of crap Americans are willing to swallow when it comes to advertising methods, or even just profit in general. Your whole society is rife with abuse. There's robo-calling, giant billboards, attack ads, pharma ads, ads or contests that are literally scams, just a few from the top of my head. Probably more I don't know about (ads to target children? there is NO good way to argue that children "should" be targeted by ads).
It's a small miracle you managed to push a mandatory "unsubscribe" link underneath mass email lists. I suppose it's mandatory because given the attitude to this kind of abuse I doubt they would put them there voluntarily.
Also, you've seen what happened to the online ad industry without this kind of regulation. If you don't make rules they're going to push it as far as they can. It's gotten to the point where people recommend adblockers for security not getting rid of annoyance. Or for saving about 95% of your mobile data plan surfing sites. Did you ever notice the most profitable ads pay for the shittiest content? The system isn't even working.
However I think websites should be able to block access to anyone they want. It doesn't seem fair to force websites to serve an audience if they do not wish to.
However, if they say "press here to forego your privacy or we'll block you", then that's not a freely given consent to forego your privacy, and in this case this "consent" doesn't count as consent. In this case they're not allowed to track people who "consented" because they didn't really consent (both in moral and in legal sense). Consent "counts" only if it's freely given, if people really want you to do that thing; in EU privacy rights are not something that can be sold or bartered away.
It's somewhat comparable to consent to sex - let's imagine that in a place where you can freely fire workers at will, you say "consent to have sex with me, or I'll fire you". You technically can fire them, but that "consent" isn't really consent, and even if they "agree", that's still nonconsensual. Privacy (in EU) is pretty much the same.
I'll take freedom any day over someone telling me that they know better.
Obviously you cannot do whatever you want to a person who physically enters your business. This is a facile point. The same is true of websites: simply because a person navigates to your website, you do not automatically have the right to place tracking cookies into their browser.
