> The thing that didn't make sense with this app: who would ever want to scroll only AI generated videos over a combined feed?

It's not an exaggeration to say that this is how millions of people use Facebook. It might be not how most HNers use it, but create a new account and you will be absolutely funneled toward prolific producers of video-based AI slop.

But the problem is that FB and Tiktok (and to a smaller extent, YT Shorts) have cornered the AI video doom scroll market, and no one really seemed to be inclined to use Sora and related models for anything more creative. Which probably made it not worth subsidizing.
