"Hi, I'm calling about your recent interest in furry related content. We at Furry Fetish inc recently mailed you a catalogue of our products... Oh...you haven't recieved it yet? Well, no worries. It was sent to 324 North Street..oh... You live on 325 North Street? No worries, your name is printed in large so whoever received it knows that is was for you and will probably deliver it to you..."
Interest based ads that everyone who has connected to the same wifi as you will now see. And it's not just interest based ads. They will use this to calculate your whole personality and manipulate you and others based on that.
Google's new ad system is called Topics. If you want to understand how it works, I would like to point you to Security Now Ep 935 in which Steve Gibson gives a pretty thorough analysis.
Marcus' take in the image is overly simplistic and a bit FUD. The intention is for Topics to replace current ad tracking systems such as tracking pixels and other metrics. In conjunction with implementing Topics, Google is removing third-party cookies from Chrome, which will eliminate most of the current invasive tracking tools.
I'm not really a Google fanboy and I'll probably just stick with Firefox personally, but everything about Topics sounds less privacy invasive than the way things are done now. If Google can force this change on the internet advertising market it will actually be an improvement for user privacy.
It's not overly simplistic. It's simply not a privacy feature if the core functionality is sharing your data. Privacy is if they stopped sharing data. Sharing more data is antithetical to privacy.
Theoretically, Topics doesn't track anything beyond general interest categories (e.g. fishing, shoes, technology, dancing, etc) and would replace current data collection systems for targeted ads. If actually implemented as described, it would result in the ad market collecting and sharing less data on users. Basically, Topics is a step in the direction that you're talking about.
So with Topics and the removal of 3rd party cookies Google can then have a monopoly on behavior based ad tracking since they also have 64% of the browsing market. This is also bad.
This is absolutely the big problem. Google already has a near monopoly on internet advertising, with Facebook/Meta being their only real competitor. If Google has full control over the interest tracking/targeting technology and it's inescapable because it's part of the browser engine then they are effectively the gatekeepers of all internet advertising. Meta could still operate as an advertising agency but wouldn't be able to implement any of their own technology, they'd have to just use what Google allows them to.
Definitely bad, but is it worse than tracking pixels (which came out of Facebook Beacon)? From an end-user privacy sense, I think Topics might be better as it doesn't keep track of your specific web activity, only general interest categories for the websites that you visit within a period of three weeks - and the record is kept locally in your browser, not on a corporate server.
Other browsers have been blocking third-party cookies for quite a while, so I cannot imagine any ad network which doesn't already have alternative solutions in place and is therefore simply given more identifying data by this system. If Google genuinely wanted to change the ad model, they'd block tracking scripts by default.
I mean...yeah? Is anyone surprised or shocked when Paramount Pictures releases a new movie? It's literally Google's whole business idea, they sell your data.
Ad/trackerblocker are inbuild in Vivaldi, customizable with own filterlists, even blocks Cookie Advices and Anti Adblock warnings in Desktop and Mobile. I can use Extensions from the Chrome Store, but no really need them, most extensions are redundant in Vivaldi.
you see, they respect the fact that you are a poor slob and there is no point advertising BMWs, large TVs and individual pillows to you. So they are making you less miserable about all the stuff you cant afford which is somewhat nice to your privacy isnt it?
"For anyone unaware, Google Chrome is currently rolling out an update that tracks your interests based on browsing history, then share them with 3rd party websites. The notification page makes it sound like they added a new privacy feature, but in actuality they automatically enrolled you into their tracking system and you have to go and manually opt out."
There's a screenshot of a pop up from Chrome that says, "Enhanced ad privacy in Chrome" with some marketing spin on how you get more choice on the types of ads you see.
