I don’t know what you mean here:
When they clearly state that signal is the best of the bunch.
If there’s one messenger the article would recommend (and I am not surprised), it would be WhatsApp. It’s fully encrypted and has the largest install base, which means many of their friends and family likely already use it.
While we all wish Signal were the default messaging app for everyone, the reality is that it’s not. Signal doesn’t have the same install base as WhatsApp, which is in the billions.
Despite its flaws, WhatsApp is still a better option than iMessage or Google Messages with RCS. This is because everything is fully encrypted, ensuring that your texts, videos, and calls remain private.
Of course, there’s the metadata issue to consider. (They do know your IP address, phone number, usage logs, location data, and the contacts you’re messaging or talking to, but not the content of those conversations because of the end-to-end encryption.) Consequently, thanks to end-to-end encryption, your texts, videos, and calls remain safe from prying eyes. Moreover, the backup feature is now fully end-to-end encrypted, eliminating any concerns about data security.
