It is safe to say, optional services get little adoption. Look at email, of the tens of billions of email addresses, there are orders of magnitude lower numbers of pgp or gpg keys. Similar experience with telegram encrypted chats. So having the option of e2ee in a communication platform, is not having it in practice.

Nice. It wasn’t there last time I checked.

I wonder what percentage of WhatsApp users backup to Google cloud, and what percentage of those use encryption.
