> There are other things to criticise with WhatsApp, but not that.

Nitpick: Facebook can obviously grant themselves the ability to read your WhatsApp messages, by pushing out a new client. What they can't do is covertly read your WhatsApp messages: WhatsApp is well-studied enough that people would notice the malicious client update within a year.

Google or Apple can also grant themselves the ability to read your WhatsApp messages. Someone grabbing your phone while it's unlocked has the same ability.

Absolutely, and this is why one of the only viable options for truly private communication is Signal on a degoogled ROM like Graphene. Matrix also works, but you need your server.

Nitpick indeed, but correct :-)
