Meta Messenger

Messenger's primary findings live in the Meta row in Consumer Apps, and the one that belongs here is the encryption timeline: Messenger did not have end-to-end encryption on by default for most of its existence, and users overwhelmingly believed otherwise because WhatsApp - the same parent company - did. Two products, one owner, opposite defaults, and no point in either interface where the difference was made legible. Cross-ref the Meta AI row in LLM Providers for the October 2025 change routing AI chat content into ad targeting across Facebook, Instagram and WhatsApp with no US opt-out.

Legal notice. PUBLIC COMPANY (META). Service route: c/o General Counsel / Corporate Secretary, Menlo Park, California — the corporate address on the SEC Form 10-K cover page is the official address of record. Confirm the exact street address on the current 10-K at sec.gov/edgar, and check the state-of-incorporation registered agent (usually Delaware; most large filers use The Corporation Trust Company or Corporation Service Company) via the Secretary of State business-entity search. A registered agent MUST accept service, which is why it is the reliable channel when a company publishes no privacy address.
