But they are not instructionals on how to commit crimes. They are instructionals on how to bypass security systems, and that may or may not be a crime depending on your relationship with the entity controlling the security system.
The same argument could be used to ban any videos showing weapons being used (target practice or demonstration dummies) or any martial arts. Because who knows whether viewers will use that knowledge against live targets. That would include a ban of all military combat and training videos.
Importantly: understanding how to bypass security systems is an implicit dependency of understanding how to defend oneself against your own security systems being bypassed by others. Instead of allowing ordinary people to educate themselves on how they might go about defending themselves against cybercrime, YouTube has effectively decided that "nah, it'd be better for the common folk to be entirely helpless to cybercriminals".
