But Google doesn't know who you are when you're in incognito. They famously "don't do fingerprinting". Of course, if Amazon or Facebook or the Times tell Google or at least hire someone to figure out who you are and tell Google then it's surely not Google who is tracking you. And likewise, if Google Tag Manager and Google DoubleClick Ads make it easy to add and integrate with the one or two missing pieces from third parties to make this work, then it's not Google's fault either.
