Can you keep elaborating about the abuses that WhatsApp has been caught red handed with?

You mentioned only unencrypted OS backups (which were a major issue, but also industry standard, affecting everything but Signal which takes a severe usability hit over it, and apparently fixed https://faq.whatsapp.com/general/chats/about-end-to-end-encr...). "Filtering content on the edges" is a whole debate but not something that ever materialized.

It sounds there's a list, what are the others?

Didn't they stop people from forwarding certain messages? https://www.nbcnews.com/tech/tech-news/whatsapp-limits-forwa...

"The Facebook-owned smartphone app said in a blog post that once a message has been forwarded from one user to another more than five times, anyone getting the message will be able to send it along to only one other person or chat group."

They can't read message contents.
