Key Structural Finding
WeChat represents the theoretical maximum (p=10, h=1). WhatsApp achieves the highest escape cost through messaging ubiquity. TikTok proves 1.56B MAU with 1hr 35min daily means nothing structurally when the algorithm, not the graph, drives retention. X demonstrates active erosion: rising substitutability from Threads and Bluesky is measurably decreasing B quarter over quarter.
