For platform managers, these results highlight the strategic importance of retaining top creators to sustain both direct and indirect content supply. Managing star departures effectively is crucial for ensuring a stable content ecosystem. Efforts to counteract negative spillovers may include incentivizing content diversification and mitigating reliance on individual stars, for instance, through enhancing visibility and monetization opportunities…
