Agreed, Google is unlikely to stop trying to track it's users; it's too profitable.

On the other hand, privacy is more about choosing what you share than not sharing things, and imo Google does an okay job at letting users control what they share; better than most companies operating at that scale. And while their privacy controls are not very fine grained, there seems to be an emphasis on making sure even non-technical users understand what is being shared and why.

FWIW, https://myaccount.google.com/activitycontrols to control what data they'd use and how it's used, and http://history.google.com lists the data they've collected. You can delete some or all from there.

I highly doubt it and derived data are actually deleted, it merely stops you from being able to view it.

That's a pretty serious claim. Do you have anything other than scepticism behind it?

[Disclaimer: I work at Google. Every team I've interacted with takes this very seriously]

Agreed, and I don't want them to quit using my data altogether. A lot of their best products are powered by my data (search, inbox, assistant)
