More of the old. They're still clenching their "modern C++" that we'll see responsible for 80% of vulnerabilities in the future.
In a sane world it would be required by law to develop and use safe designs, starting with safer languages. You don't get to build a bridge you know will collapse and avoid the consequences. As govs continue to understand tech and apply the laws they conveniently forgot about, orgs will be held accountable.
I assumed you meant why not using Rust? I guess Rust is not a silver bullet for secure application and the last thing they want to do is to force everyone to convert to Rust or D language for HPC [1].
