In case he doesn't, I'll do so on his behalf.

Compared to proprietary hardware and software, it's far easier (not to mention more efficient, due to voluntary contributions from coders) to patch any potential security vulnerabilities with open software (especially if it's part of open hardware, assuming THAT doesn't have its own set of potential exploits) owing to its transparent nature.

Of course, both proprietary and free software are obligated depending on region NOT to immediately patch certain exploits and vulnerabilities so that the government can take advantage of it. The difference is that it's more transparent when this happens (albeit only slightly) with FOSS software and especially hardware.
