The walled garden is basically their entire moat. If you have access to that, you can do things like, "Every hour, write all updates in chronological order to a file $HERE", then you have an API feed. You integrate that into your own homespun app, then you never see their ads. They hate that.

All of Meta's products have to be user-hostile, because the first thing you want is interop and that kills their monetization.
