Why do you think complex algos, complex feeds, across large search space (all content instead of friends and family) turns out to be more profitable? Are ads suddenly more valuable in that context? I don’t think so. And it’s certainly much more expensive to operate than a simple chronological feed of friends and family.
It comes down to time spent. People spend more time on the apps and see more ads. We can argue over whether that’s a sign people like the app more… but no one is being forced to scroll a feed they don’t enjoy. Interesting that people “are begging for changes” yet using the apps more and more anyways.
