Who has the keys? What exactly is encrypted? 1-2-1 chats? Group chats? Attachments? Are metadata handed over? Dear Autumn12 don't just read the marketing material.

In a real example: Apple's Cloud has a copy of most users' data as (by f...g default) when you activate an iphone it enables them all. I remember the case with that terrorist (was it the Boston Marathon guy?) that Apple wouldn't hack the device but they handed everything they had on their cloud to FBI.

I don't know what you want to say with your example, but there are dozens of examples where telegram did not give out data even thought they likely should have. It's definitely a more private choice to apple or meta

Yes, but not by default, and it’s weird/custom and not properly peer-reviewed.

> somewhat better than meta AND the whole US government having access to my data

How do you know that that is the case for WhatsApp?
