You should not consider Dropbox a file storage and sync provider, anymore. Dropbox (and almost all other big established storage/sync providers) moved to a new territory (market) called Content Collaboration Platform. This contains applications which provide comprehensive capabilities that support use cases from productivity and collaboration to content protection and infrastructure modernization. As some of you already mentioned, there are several reasons for it:
1. File storage and syncing is commodity. It is quite easy (compared to what was 5-10-15 years ago) to create a sharing & syncing capability software. Also, there are AWS/Azure as infrastructure so no one needs to handle this part of the business.
2. These big providers move to small-medium business and enterprise sector from personal users. It easy to understand, an enterprise contract with 5000+ users a year is much more profitable than acquiring loads of personal users who do not want to pay at all most of the times.
3. Lastly, big companies want to buy an integrated solution, which handles not just one thing well™, but contains extended functionality and support external providers. In Dropbox's case its file commenting, Zoom & Slack integration, etc.
