alt Hacker Newsi worked at google for 18 years. they certainly "know" you don't like ads, and they definitely don't care. they may also "know" your consumer account is a safe place to dump all the non-converting impressions they need to burn somewhere, but even if you could prove that, they wouldn't care. tbh, whenever somebody comes at me with tin foil hat assertions i point to this exact hilarious scenario as why i do not believe they are actually surveillance-oriented business a la the palantirs of the world. i think their ideal state is 100 trillion anonymous bank accounts they can pull from, not 8 billion unique human profiles to care about.
Google's culture is to just burn ungodly amounts of disk space as a kind of flex for how important a team's project is. So every Google service is collecting as much as it can, all the time, with legal counsel and some "oh we value your privacy" sophistry going on.
If you still work for Google I recommend reading privacy design docs for random large scale services if you're able. It's very telling what the priorities are.
And I agree that they mostly don't want to be Palantir-like. They mostly don't care about people. They care about advertisers. Any new targeting mechanism they can offer advertisers they absolutely will. The problem is they sit on a gold mine of very, very sensitive personal data (most of it "anonymized"). Most of it can be de-anonymized with little work. Worse, they will absolutely cough it up to the government when required. They also have a lot of motivated engineers thinking of ways to try to use said data to "improve products". Like the whole saga of doing activity inference for Android users. You don't even want to know about how stupid and creepy that is/was.
