Conversely, foregoing additional ad revenue and other benefits of using emails from the relatively few number of G-Suite accounts likely has an incredibly small direct impact on the bottom line. I can't speak for any internal data Google has, but my guess would be that individuals using G-Suite accounts are more likely to use Google services in their personal lives. Any lost benefits or ad revenue would be easy to write off as a negligible loss leader. Heck, with how common G-Suite is used in schools, getting kids used to Gmail early would be a powerful argument on its own. Though writing it out like that kind of feels a bit dirty.
