That line of reasoning seems specious. Everything that runs on a computer is run as, or by, native code at some point, and that doesn't make it automatically insecure. At the same time, since Electron uses a browser, any potentially unsafe native code in the browser is loaded and waiting to be exploited anyway when using this viewer. Finally, I think most people (myself included) trust their browser developer more than they trust a random person's Javascript thrown on GitHub. That said, I don't see why anybody would use this over mupdf or evince.
