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?

Yes, what’s app messaging specifically has a long history under Facebook of giving away user data like candy to anyone who wants it, including the content of private messages. It’s been shown repeatedly and is common knowledge yet they still have yet to do anything to prevent it. this here is a declassified internal document from the FBI highlighting what they have access to and what level of legal request they need for what. Notably message content requires no legal request to access

I think that photo goes against the claim that WhatsApp can decrypt or otherwise easily get access to message content

Message content: Limited

if target is using iPhone and iCloud backups enabled, iCloud returns may contain WhatsApp data, to include message content

Also was that before the full encryption of the backups? Someone else posted a study about their backup encryption where they concluded that it at least seemed secure (with the caveat of it being a proprietary app).
