I also wonder how many users are aware of the imperfections in the end to end encryption in WhatsApp.

Thanks for posting this!

I used the wayback machine to read the older version of this article, it took specific aim at WhatsApp and Sigal, indicating that (in so many words) it disapproved of the apps providing a notice of Safety Numbers changing instead of the app flipping its wig and making the user take affirmative action to continue communications, otherwise it wasn't true TOFU.

I have about 30+ contacts on Signal, and I almost __never__ get Safety number changes. I certainly don't think making the user click through yet-another-dialog-they-wont-read will be a big security improvement.

I suppose I disagree with the 'not true TOFU' argument.

It shows that in every message thread, so I'd say everyone; how many understand that and realize the consequences of having or not having E2E encryption is another matter.
