Well that's a fairly misleading comparison. Where is the screenshot for Outlook.com which has no ads either?

Not to mention the fact that Gmail is valuable to Google because it gets people to sign in in all the browsers they use, allowing them to track them via cookies on all Google properties including search.

The "World's Most Valuable Advertising Business" does things like track which physical stores Android phone users and Google maps users on iOS visit.

Plenty of Android OEMs install adware and bloatware, sometimes which cannot even be uninstalled, so I guess people are already conditioned to this.
