Did anyone actually think WeChat communications are secure? Do we have reason to believe iMessage and Whatsapp are more secure?

wrt iMessage, yes, it’s E2EE and the keys are not stored in iCloud if you disable iMessage backup. Granted Apple still owns the keyset gets so, eh, depends on how paranoid you wanna get.

WhatsApp is end-to-end encrypted so the service providers themselves can't read the message content, yes, definitely. Although, technically the security guarantees are nil unless you verify safety numbers which I can guarantee almost nobody actually does.

I mean there’s a white paper on iMessage’s security, and there isn’t (i don’t think) on WeChat. WhatsApp’s encryption uses libsignal.

The security qualities of iMessage and WhatsApp is known. It’s not of WeChat.

iMessage is e2e encrypted but Apple has the key... so I would not consider this e2e....

Any time others have access to your keys the only logical assumption is that they already know. Relying on goodwill is just naive

You also have to trust the source code, or trust a recent audit, then also make sure the build you have kept it's integrity and matches the audit build.

Yep. WhatsApp is better and Signal is better still, but iMessage's level of privacy and security is more than enough for someone who isn't specifically targeted by a nation-state-level actor.
