If I recall correctly, at least for non-group chats they do use end-to-end encryption. That being said, obviously there are some practical limitations on the impact if you think that WhatsApp would actively try to be malicious, since they’re also providing the client software and could hypothetically backdoor that.

According to this, they do use end-to-end encryption for group chats too.
Maybe I’m recalling some other service or a default setting or something. Some service had non-e2e-encrypted-group messages for at least some period of time.
