"I'm not trying to make anyone paranoid[...]" You're doing a good job at it, however! Your scenario reminds me of Issac Asimov's Foundation series, particularly where the Foundation had the ability to disable its enemies' technological, nuclear in this case, infrastructure, as their enemies little understood it themselves. Coming back to reality, it's not the case that Adobe, et al, poorly understand their own software, simply that only they could see its potential problems, being as it's closed-source. I'm somewhat biased, but in your scenario it would be much better to give the souce code a larger audience, via open sourcing it, to negate, albeit not entirely, the prevalence of such government-researched 0-day exploits.
