They trust that the Guardian, a highly reputable newspaper, has spoken to experts in the field, done the research, and made this evaluation, which it accurately reflected in the headline.

Signal is only a more secure alternative in _some_ threat models. The most obvious counterexample is that, in some contexts, using WhatsApp marks you as a person who owns a smartphone, while using Signal marks you as a dissident. There are other contexts where losing messages while not being actively attacked (not even just due to this design decision; Signal ultimately just does not have as reliable infrastructure as WhatsApp) is more dangerous than WhatsApp's resend behavior.
