Shared family streaming accounts are a compartmentalization failure disguised as savings.

Every profile feeds one behavioral model. Viewing patterns across all users collapse into one household record — one subpoena retrieves everything.

The Privacy Spectrum (Polyonymy): distinct identities prevent cross-contamination. Shared accounts dissolve that.

Separate accounts per person keeps each person's behavioral record independently non-attributable.

Each household member should operate under distinct credentials with no shared payment linkage where avoidable. Viewing behavior, search history, and content preferences aggregated across persons creates a richer combined profile than either alone.
