And what you're linking to is NOT what you described, "in order to provide more targeted advertisements".
Your links are describing Gemini integration. If you ask Gemini a question about your e-mails, obviously it needs to look at them. If Google is suggesting a smart reply, obviously it needs to process your e-mail to do so. But these are features designed to benefit the user.
You were talking about target advertising. That's not what your links have anything to do with.
[0]: "Google publicly announced in 2017 it would stop using Gmail content for ad targeting but continued to scan emails for spam, malware, and other non-ad functionality, which leaves room for ambiguity about downstream uses of metadata or other signals"
Who cares why Google is reading your emails? Not me.
Oh, it's just for non-ad functionality? In that case, go right ahead!
