Yet. Until they say "We delete these messages after X time and they are gone gone, and we're not reading them" Assume they are reading them, or will read them and the information just hasn't got out yet.

I mean we keep finding more and more cases where companies like FB and Google were reading messages years ago and it wasn't till now we found out.

They never had the plaintext of the messages in the first place, so they don't need to delete them. That's what end-to-end encrypted means.

Whether Facebook/Meta can read the plain text of the messages or not depends on whether that encryption is "zero knowledge" or not, aka: does Facebook generate and retain the private encryption key, or does it stay on the users' devices only, never visible to Facebook or stored on Facebook servers?

In the former case, Facebook can decrypt the messages at will, and the e2ee only protects against hackers, not Facebook itself, nor against law enforcement, since if Facebook has the decryption key they can be legally compelled to hand it over (and probably would voluntarily, going by their history).

They use the Signal protocol. The keys are not generated by Facebook, and are never on their servers. They are generated on the devices themselves.

They don't need the plaintext if they have your key. Since they wrote the application you have zero clue if they do or not.
