Of course, but the article specifically says that Gmail does it for advertising purposes, which is no longer true [1].
It's pretty reasonable to expect that your email provider is going to "scan" your message content. Performing spam detection, for example, is a pretty common reason and most people want that. Tutanota scans message content: "executing content checks and mark emails as spam or not" [2]. So I don't think they are demonizing message scanning on it's own. If there are objectionable purposes for Gmail's message scanning, let's call those out.

This appears to be false. From Google (https://support.google.com/mail/answer/6603?hl=en):
> We will not scan or read your Gmail messages to show you ads.
