Frankly, I don't trust enough to believe they won't change this in the future, or even that they're telling the truth now. Tracking people is the only way Google makes any money.
Actually, that's false. Most of the money Google makes from ads are not behaviorally targeted ads, but keyword targeted. If you subtract out YouTube 'behavior target' which seems more targeted based on what you watched, the portion of money Google actually makes from using 3rd party website tracking is quite small.
Agreed. I recently discovered that they even track you when using incognito. e.g. I got a youtube suggestion whilst in incognito that I had searched for 2 weeks prior & the type of search precludes the possibility of it being a co-incidence. So much for no cookies in incognito...
Incognito mode doesn't block cookies, it creates a separate cookiejar. If you have the same incognito session open for two weeks, every cookie from every site you visited still exists. If you want cookie-clearing behavior, you'll have to periodically close your incognito window.
