1. I can’t find a link to this but I’m sure I’ve read an article about what happens when you “report” a message someone sent to you in WhatsApp. In this case some reviewer at Meta will look at your message and determine if it violated the rules. IIRC the article talked about them most likely being added to the chat but not visible.
2. There’s a recent lawsuit that shows that Meta can view your messages through internal systems: https://proton.me/blog/whatsapp-encryption-lawsuit
3. Meta’s AI assistant in WhatsApp leaves more questions about privacy. How closed-off is the data used in this AI from other parts of Meta’s services?

This is an important open letter. I hope legislators read it

I also hope we get better and better Linux phones
