For open source messengers, you can check whether they actually encrypt your messages and whether the server has access to your encryption keys but what about WhatsApp? Since it’s not open source, you can’t be sure that the encryption keys aren’t sent to the server, right? Has there been a case where a government was able to access WhatsApp chats without reading them from the phone itself?
Facebook owns what’s app and they can read any message on the service, they’ve also been known to give logs and messages to law enforcement agencies at request without warrants.

Group chats are also end-to-end encrypted in WhatsApp (so any monitoring would need to be done in cooperation with one of the participants’ devices before encryption or after decryption)

In a subpoena case in India, that turned out to be not true.
Source please.
WhatsApp admins hold keys to being able to do that under law pressure.
How do they get the keys?
They only guarantee it for 1-1 messages and statuses, and against “generic” actors for group chats…
Who is “they”?
