The original suggestion by Glenn was to say that remote HTML content is
a potential security risk. That's a statement of fact and I gave
supporting evidence. Those risks apply to Emacs users, but I don't think
anyone proposed "be afraid" to be the message we should give.

Certainly. The FAQ can link to external resources, for instance. I think
in the FAQ we should at least list the libraries that Emacs uses to
render remote content (SVG, XML, PNG, etc.) so the user is aware of
those dependencies and will keep them up to date.
But the method for that depends on the platform, so... do we explain in
the FAQ? Does Emacs itself warn when libraries are out of date? I don't
know.
Ted
