This was going to be the compromise that would allow Chrome to have a path towards deprecating third-party cookies without massively decreasing its ad revenue, but they've walked away even from that: https://privacysandbox.com/news/privacy-sandbox-update/

> Instead of deprecating third-party cookies, we would introduce a new experience in Chrome that lets people make an informed choice that applies across their web browsing, and they’d be able to adjust that choice at any time. We're discussing this new path with regulators, and will engage with the industry as we roll this out... We'll continue to make the Privacy Sandbox APIs available and invest in them to further improve privacy and utility.

Discussion here: https://news.ycombinator.com/item?id=41038586

There are numerous ways that the Topics API could leak sensitive information (say, for instance, increased values for a set of topics statistically related to life events with legal/health consequences) - I'm glad that opposition is being highlighted.

Apple's opposition comments are also worth reviewing: https://github.com/WebKit/standards-positions/issues/111

Google's defense is apparently "well it's better than 3rd party cookies"

Well we're getting rid of 3rd party cookies... so like, that was the absolute minimum bar.

It's a curious list of topics: https://github.com/patcg-individual-drafts/topics/blob/main/...

Does anyone know how the taxonomy was created.

The irony of telling people how to use something you're opposed to...

It's clear that mainstream browsers have become the exact opposite of user agents. Unfortunately I don't see an easy solution to that problem beyond educating web developers and users, to change course to avoid all this hostile complexity, and possibly creating more alternative browsers that explicitly don't support things like this (or will lie about it to preserve the interests of the user: https://news.ycombinator.com/item?id=36935843 )

Hypothetically, what could the modern web look like if instead of inferring user attributes we let users specify those?

E.g.; I tend to want recipes by French authors. I have a profile set up in my browser to search in French, prefer French results, and when localization is applicable to retrieve results written in France. Switching to this profile is a button-click and automagically affects what all websites I visit believe out my personna.

E.g.; In that same example, even ad-tech presumably benefits from believing my ruse. If I'm in a mood to read French recipes in French, an ad for a US Football game is probably not going to land very well. Perhaps some company could do better by targeting based on both who I am and who I'm purporting to be (especially with respect to important life characteristics like log10(salary) and count(children)), but the temporary personna is by itself likely already better than any inferred characteristics at guiding targeted ads.

E.g.; I throw on a DIY personna. Instead of being inundated with (mostly fake) repair services when I ask for bike or device repair information, I find links to solid content like Sheldon Brown's blog and commercial links to informational content, DIY-focused parts and tools for sale, .... The web can still be a for-profit, sanitized entity while providing a vastly better experience for me the searcher and also the poor sucker paying for "bike repair shop" ads on my searches which could never possibly convert for that concept.

This looks like anti-privacy with extra steps. This breaks the disconnection that iframe provides. Kind of like turning iframe into a detective. Were you interested in tennis on the night of January 3rd?

> Infer topics of interest from the site URL

Isn't this just naive and may not actually produce useful results for most sites?

Oh look, an easy new way to fingerprint users.

Break up Google fast. We need tech to return to the true hacker spirit.

Is there any way I can find where this topic information is stored? I presume it's a SQLite database in the profile folder, like the cookies and history.

Are there extensions that disable this?

I seriously do not understand why people use Google Chrome and other Chromium derivatives.

It's one thing that my non-tech sphere friends do, but I see so many people at work just defaulting to using Google Chrome, and I frankly just cannot fathom it.

Like, FFS, is browser sync that useful? In 30+ years using the web on a bunch of different computers, I have not once ever been like "ooooh I wish I had the 35+ tabs I had open on my work computer on my personal one".

Yet another step into ChromeOSissification of the Web.
