Hard disagree. I'm a security engineer by training and actually learned C at university among other languages. Most security weaknesses are human error. Therefore most used and therefore read and audited code tends to be the most secure. C is a perfectly reasonable language for low level things like embedded controllers where rust is hard to get. But safer by design is always more reliable than skill or willpower or even experience. So its just not likely that his C code is safer than something written in current technology. I get feeling comfortable in a language, but that should not ignore technological progress. I'm not a fan of all thee rust hype, but in terms of security it is a signifikant leap forward and feels alot like C.
