> Unfortunately, Google is a very much technology focused and not business focused. That’s why after 20+ years almost all of its revenue still comes from advertising. All of the other major tech companies have multiple billion dollar profitable revenue streams.

Is that true of other ad-tech driven companies as well? Companies like Meta and Twitter.

Companies like Amazon, Apple, and Microsoft are used to charging users directly for some good or service. It may be that they are just better positioned to establish those other revenue streams.
