I wonder when google is going to tap into Gmail data of users (if they do not already). They must have trillions of english messages and they already filtered spam. Additionally, it’s hard to ever prove that they did it.
Maybe it doesn’t make for high quality data though, not sure…
Ever since I used a browser, both Firefox and Chrome always clearly stated, that Incognito Tabs are not private browsing, and they said so in every Tab in very clear terms. Why is that controversial then?
