Chrome 69 will keep Google Cookies when you tell it to delete all cookies | Hacker News
In Chrome 69, the behavior of the login function has been changed and it is a specification that logs in to Chrome automatically when logging in to use Google services such as Gmail and Google Documents. However, it is pointed out that this automatic login function has a privacy problem.
GIGAZINE notes that it is a "dark pattern" that tricks users against specification changes when logging into Google services on Chrome 69 automatically logging in to Chrome -
Christophe Tavan, CTO of Digital Media / Contentpass , notes the phrase "I will never sign out from my Google Account" that appears when deleting cookies on Chrome 69 and " Delete cookie '' Thank you Chrome 'and sarcastically commented tweets.
After Mr. Tavan actually cleared the cookie on Chrome 69, I checked whether cookie was left, and there was a surprisingly only Google-related cookie left. Chrome 69 said that even if cookies were deleted in the way advocated by Google's support, only Google's cookies were instantly recreated.

On the other hand, Parisa Tabriz , Google Chrome development team leader, said, "As long as you are signed in to Chrome, Chrome creates and restores Google's authentication cookie," allowing Chrome to recreate the cookie I did not invalidate the authentication cookie unless I log out.
To be clear: when you click "Sign out" in either Chrome or a Google site, we sign you out of Google. Period. Or you can just visit https://t.co/aWJlvCYqGT . Signing out makes your auth cookies invalid . 3/4 pic.twitter.com/WJetLhMWke- Parisa Tabriz (@ laparisa) September 25, 2018
Mr. Tabris has commented on this subject "We are planning to change the specification of Chrome 69".
