[1] I do note that you're the one caveating here, by trying to qualify "access" meaning "targeted adverts and content", which needless to say is not actually access to the data. Extensive attempts have been made over the years to try to deanonymize the ad feed (as often as not to get clicks at sites like this) and only a handful of holes have been found. There is no access to the data, period.
You can use that service to get enough context clues about certain targets to identify someone [0] [1]. Will most advertisers do this? Not five years ago but it's vanishingly easy now to get an LLM to gin up bespoke algorithms that will do it for you. And the door between Google's servers and federal LEOs has no latch and they share plenty of byte-for-byte data with agencies like ICE (which is literally one of my links).
I don't understand the point of being so hyperfixated on word choice since this is just Hacker News and not a court of law. But I suppose everyone makes their choices for a reason even if that reason has more to do with some reactionary and emotional outburst rather than any actual substantive additions to the discussion.

The bottom line being that what you have amounts to a plausible security flaw. Which the market has been treating as such, reasonably effectively.
Yet you are all claiming that Google is literally offering "here's user data for sale at a price". Which they are not and never have. And that's not the same thing, and you know it.
It's one thing to claim a company's product is bad or insecure. It's quite another to lie about them. And fine, that produces a (sigh) "reactionary and emotional outburst". HN used to be so much better about rational discourse. Now it's all about who our enemies are.
Now, can you PLEASE try to restate your complaint in a way that isn't just a lie? Maybe construct it about how the "exploit" data that they hold internally? It can be done. But not like this. This is lying.
