Privacy conditions

The court-appointed privacy ombudsman recommended approval with conditions: Tonic.ai de-identifies the email, a certification is filed before each transfer, and the buyer publicly commits not to re-identify, with that commitment flowing to downstream recipients (The Next Web).

Objections

Unions including the flight attendants (AFA-CWA) and pilots (ALPA) objected over re-identification risk. On October 9, 2026, 120+ members of Congress urged excluding employee data (Senate Commerce).
