A counter-intuitive take: Facebook may actually do better as a business as high-resistance users leave (for the same reason spammers keep their messages intentionally faulty).

From an optimization standpoint, knowledgable, hard-to-rile-up users are mostly noise. As they churn, the remaining user base becomes more homogeneous and easier to optimize for engagement and ads. Churn effectively acts as a filtering mechanism.

So what looks like decline from the outside may just be the system converging on the segment it extracts the most value from. From Facebook’s perspective, that’s not collapse - it’s specialization.
