And if so, why exactly? It says it’s end-to-end encrypted. The metadata isn’t. But what is metadata and is it bad that it’s not? Are there any other problematic things?
I think I have a few answers for these questions, but I was wondering if anyone else has good answers/explanations/links to share where I can inform myself more.
Sure. My point is that, as far as I believe anyone is currently aware, there is no evidence that any law enforcement agency has ever accessed the content of encrypted WhatsApp messages. That does not mean that it has never happened either, but anyone positively claiming so is doing it without actual evidence, which is something we should probably avoid doing.
We can assess the security of the app though. And we should. And we should also bring awareness to the problems of closed sources.
