The overarching theme I'm seeing is one of FB jumping into whatever format bored people turn to, then slowly cramming it w/ ads until those eyeballs drift to the next fad, rinse and repeat.

Regardless of how one might dislike it, the "generate outrage => show ads" thing has been working just peachy for Fox and friends. So my cynical take is that FB will continue to do just fine even as people shift to different consumption formats, and even if tiktok took over the world, because fundamentally, bored people will always exist and fads come and go.
