That would only be a headline if the VPN software were somehow camera-specific, which seems unlikely. That fact alone is a benefit to using general-purpose security tools: more eyes on it, making a zero-day that much less likely (and a fix that much faster). Another benefit is that updating a single instance of firewall or VPN software is much easier than updating dozens of cameras. Of course, if there are more VPN clients than cameras, that ceases to be true. Adding such a layer is also just a kind of defense-in-depth. With the instant example, both the cameras and the VPN software (or firewall) would have to have vulnerabilities, at the same time.
