I think you're discounting the fact that the software with the bugs was written in C precisely because C was a better fit than the other languages which offered greater protection.

I'm not saying (and have never said) that C is better than other languages for every problem. I'm just saying that I read too many articles about the "problems" with C that Stupid C Programmers must not realize since we keep using it where the author of the article hasn't bothered to understand why programs are written in C in the first place.
