The amount of people who apparently don't get this is insane. Incognito mode is always, and has always been, about preventing your browser from saving history locally, so other users on your computer won't see what you've done. There's a reason they always use examples like going engagement ring shopping or planning a surprise party. Of all the underhanded things Google has done, this is not one of them. Chrome has always been very upfront that websites, ISPs, and network administrators can still gather information about your browsing.
