That is true but you have to be very specific about who your "users" are.

If your "users" are the guys in charge of showing more ads to people, then yes. People, on the other hand absolutely prefer watching their contacts' posts first. Recommendations related with their individual preferences, second. Random dopamine-inducing stuff, only from time to time. If you prioritize the third kind only is like someone said already on the commments here: like a restaurant that only serves candy. They will have customers for a while but eventually they will burn them down (or kill them).
