In the actual case that got this change in messaging put in, the guy signed in to his Google account from incognito & is mad that Google kept the data from his incognito session. There's nothing in the court case Google is responding to about them using other tracking systems. People seem to want to believe very much there's lots of backchannel tracking & special privilege & self dealing going on at Google. But theres no evidence, there's people vehemently swearing Google does have strong internal information firewalling to prevent this abuse, and it's not what this court case is about. The court case is about users expecting incognito to be a magic cloaking shield where anything you do on the web in incognito magically doesn't stuck around after the fact.
