For browsers that implement strict cookie partitioning, the privacy concern is moot. With this, the cookie jar that's used when chatgpt.com is a 3rd party site is completely separate for the jar used on the 1st party site. So your chatgpt.com account can't be linked to your ad views.

Since this has been standard ad tech for awhile, browsers have reacted to this to implement cookie partitioning for exactly these privacy reasons.

This is why you use Firefox that keeps the cookie jars separate (by default, AFAIK). That should prevent this specific implementation, shouldn't it?

And the number of websites with ChatGPT ad trackers is on track to be doubled from last month.

Yuuup. tracking consumers and finding spending correlations to exploit was the entire reason for the "Data Science" and "ML" pushes that got us here.

why is OpenAI wasting their efforts on implementing ads if they are apparently close to AGI?

https://tinfoil.sh/ - ultimately there is no guarantee that the LLM provider isn’t spying on you, but at least tinfoil claims to be unable to do so.

Incredibly creepy. I'm amazed they don't have any idea quite how user-hostile this is, or the reception it would receive.

This might help:

Does this look right? AdGuard style.

> The mechanism is standard adtech. What has no precedent is running it on an AI chat product.

Doesn’t Gemini or whatever Meta’s agent is do this too?

Time to start having separate container for every domain. I'm pretty sure this should be possible in Firefox.
