Actually it's more like as technically literate people we forget just how little we know about subjects other than computers - in this case, law. When Google, the company, offers a product marketed as "incognito", it's reasonable to think that Google, the same company, will avoid tracking users of that product - regardless of the technical details involved. The problem here wasn't Google failing to educate users of technical shortcomings that leave users vulnerable to third party surveillance, but rather Google failing to respect their own large print representation.
