That's their current corporate strategy. Strategies change over time as markets evolve. That's a given despite current state. Companies need to evolve and defend their position.
I never made a cent with prior sites because I barely used FB, never used other sites except passively of late to follow crypto, and don't like the lack of privacy. I've had friends do very well marketing themselves on Instagram to quit their jobs, so it's possible indirectly.
Good point however people make it more here than at instagram...FB will never change their corporate strategy...it is in their DNA to use people data for advertisement money and even if FB want to change, their shareholders will never allow it because sharing revenue with billions of members will lead to no shareholders wealth maximization and that is the aim since they went public
