Meta apparently found that chronological feeds "caused people to log off" and engage less with their platform, which is why they don't like them. https://www.wired.com/story/meta-just-proved-people-hate-chronological-feeds/
Perhaps it's because they saw what they wanted to see quickly, and went on with their lives. Instead of wading through a ton of engagement fishing outrage-bait and doomscrolling their way through the day.
We know by now that high engagement does not equal healthy usage. Meta et al thrive on *unhealthy* patterns.
