I don’t know how Meta will benefit from this (perhaps they are protecting themselves from upcoming regulations in EU). Important question is who is owning the key, if they own the key, that means nothing in terms of protection against their usage. Even if they don’t have the key, they don’t even care about messages itself anymore 1. It’s risky business, regulations might hit you hard 2. Metadata is good enough for them 3. They own the client, so they know how to extract more than useful data in the end. E2EE is important marketing trick nowadays, most users see it as if this makes them completely anonymous to companies like Meta. After all ads are their only source of generating money. They will do whatever it takes to satisfy advertisers, not the users.
