I wasn’t implying human read, unless it is flagged. Most people consider parsing reading. The NSA doesn’t read your email either, they parse it unless it is flagged, then they read it, almost the same, except google is building an advertising profile and the NSA is building a risk assessment profile.
Of course data is “fed back”, that is how the parsing is able to selectively serve ads based on the content of your email, an index is generated, the ads that are served based on that index are tracked, etc.
Not to mention that google will turn over the contents of your mail to any agency with a warrant or court order to do so.
With secure email services like protonmail they can’t access the contents of your email even if they want to…they don’t mine your email for advertising data…they don’t mine the emails of people emailing you for advertising data against their accounts.
I know Gmail has been doing this since the beginning and it has been unacceptable since then. Nothing has changed about that.
