A great idea. No doubt some companies will claim this is "anti-competitive," a flagrant abiuse of Apple's market power, and will lead to anarchy, death, destruction lower profits unless the government steps in and forces Apple stop this dangerous practice...

Good. It’s about time companies recognize that people are not commodities.
 
Do I have this setup to prevent cross-tracking both in private browsing and regular browsing?
No @coolbreeze2 , you need to do two things: (1) Enable the Prevent Cross Site Tracking switch at the top of screenshot you shared, and (2) scroll down to “Advanced“ at the bottom of Setting>Safari page, tap it, then tap “Advanced Tracking and Fingerprint Protection”, then select ”All Browsing”. That will enable the feature that is the subject of this article. Hope this helps. 🙏🏽

Good, more ways for Apple trying to protect their user data from being captured By other companies, while user happens to benefit from This.
However, ad network can easily circumvent this by either cryptographically encode tracking bit to be difficult To understand by machine, or bind Tracking to website access (doesn’t have tracking bit? 404). And I believe there will be more ways to do it. They can also let AI manage all of these. Or like someone already mentioned, using unique link for each individual. Force account creation, so on and so forth.
After some time, people who value their privacy will find themselves impossible to access many websites without either registering an account or disable privacy Protection features. If the site your work rely on enforces such policy, good luck trying to keep your browsing history private without VM or similar.
Wonder how Apple will slowly combat this alarming trend.

Yes, same. Do you have iCloud+/Private Relay? I think that hides your IP address on websites, too.
Yes I have iCloud+/Private Relay activated.

This is the iOS version I have installed.

Nope, that's not how it works. Everything before the ? in a URL is a unique identifier to a page (or web resource). Anything after that can be arbitrary and doesn't affect the URL, unless the website itself is looking at (or querying) the query string.

This means that advertisers can tack on their own query parameters onto any URL without changing the URL itself. The website will only see what it needs, and ignore the rest, while the advertiser can pick up the parameters that they added.

An advertiser can't invent their own URLs for a website. They'd be pointing to a resource that likely wouldn't exist.

I'm curious how Apple's feature determines which parameters can safely be removed? As a website developer, I haven't used query string parameters in 20+ years because they are ugly, but any existing websites still using query string parameters for functionality could theoretically be broken by this feature.
I don’t think it’s as cut and dry as this. Couldn’t an advertiser just send a link in their email that has any url/path but 301 redirects you to the url with the query param?
 
What about my Amazon affiliate sites 😩 They all use the same tag.
You're screwed if people are visiting your affiliate sites on iOS.

Fwiw, brave has been doing this for some time now, and in REGULAR browsing as well, not just private browsing like safari 17
It's not just private browsing. You can set it to all browsing if you wish.
 
More details here, they appear to be using the same privacytests.org set of query strings. What’s interesting is the file gets remotely updated so they could in theory continue to add more variables to the list.

wonderful hypocrisy from Apple on tracking from other people. yet it seeks to put ON DEVICE surveillance on YOUR equipment of course in the name of something moral, but actually the precursor to backdoors to your own devices, and no doubt China will love it, as Apple has already demonstrated it does what governments like.

Didn’t you get the memo?

 
Judging from the screenshot those links would still function fine. This is targeting specific parts of URLs that cater to cross site tracking for marketing/data collection
There are any number of ways that snoopers can (and will) thwart Apple’s valiant efforts in this regard.

Looks like they'll be stripping all referers off the URL as its certainly tracking activity. The good news is people will still be directed to the product you promoted. The bad news is you won't get credited for any sales.

It will also interfere with advertising. The clicks for the advertisement will still work, but you won't get credited or paid for any performance-related activity.

A neat feature, but web tech is my forte and there are many ways to accomplish the same goal that cannot be so easily identified and counteracted.

Not bad. We got 20 posts in before the inevitable deluge of "X has been doing this for years", "it's easy to defeat", and "Apple should be doing Y instead". The first two are almost always true of any feature released by any company and the third is usually a personal grievance aired in every remotely related thread. Like my comment here. Damn.
