The article's point wasn't that Reddit is doomed, it's that Reddit as we knew it (with strong distinctions between sub-reddits) is doomed. The article basically says "let's play along and say Reddit is like feudalism - then what comes next is early Modern Governments" ie - centralization of power towards absolute centers of power. The article argues that Reddit currently employs moderators because the heterogeneity (ie, strong distinctions of subreddits) are not generally amendable to local control. In order for Reddit to transition to strong centralization that heterogeneity needs to be reduced and managed (in a form similar to how TikTok serves up content in a way that minimizes the ability of 'communities' with heterogeneous norms to form).
