Key Structural Insight

Strongest bilateral lock-in in social media. Creators cannot take subscribers. Viewers cannot take their algorithm.

Creator lock-in extreme: subscribers, monetization history, algorithm training. Viewer lock-in through recommendations trained on billions of watch hours. No substitute for both sides simultaneously.
