You, son, are woefully uninformed. You can turn off some of the most invasive uses of data which Google says it will no longer use (the legal exposure of they did would be massive so yeah, I think they are keeping to their promises). Yes, there is some still analysis but it's for anti-spam and anti+malware and it's for other things like regular old search. And no one is looking at your emails.

Also, there are "no ads that look like email." That's bullshit. Been a Gmail user for over 15 years never seen one from Google. It does have rather effective anti-spam, however.
