I don't use Chrome because I don't trust Google. I assumed they were tracking users based on previous reports.
I'm saying that i think a reasonable person would expect that their incognito browsing traffic wouldn't be monitored and passed to Google. This reasonable person standard is the legal standard for advertising and marketing claims in my country and many others.
The disclaimer explicitly calls out that your activity might still be visible to sites, you visit, your employer or school, and your ISP - they notably say nothing about Google. That kind of thing is very misleading.
Where in that disclaimer (or otherwise) would I get the impression Google will track me?
