This is an assumption that Snow knew the standards. You are making gross assumptions about Mills training and what she was taught.
While each individual is always responsible for themselves, there is frequently a dismissal by instructors/dive centers of standards ("you don't need to know that"). Customers see instructors as the expert. That doesn't absolve customers of responsibility, but the reality is that it does impact dive safety.
This reminds me of a question that came up when I was discussing this with my SO - I've never done any dive training so I have no idea what is included in OW training, never mind instructor training, but I've noticed a lot of people discussing this incident making the argument that Mills is significantly at fault because she should have known better because based on her OW training she should have refused to do the dive due to various factors (no weight check, etc.) because certified divers are ultimately responsible for themselves, or something along those lines. But being able to be independent in that way and stand up to an instructor and not just go along because of course the instructor must know best is itself a skill (and also from my experience seems a bit of a personalty type thing also - I've met some people who I think it would be exceptionally difficult to teach to have that attitude.)
So is that skill addressed explicitly in OW training? Or are divers just told "yes, you should do this, this is good" and then they were told to do so and if they don't it's on them? Are instructors encouraged to refuse to certify divers whom they believe are unable to approach diving with the necessary independently responsible attitude?
What about instructors for subsequent classes? If someone is certified by someone else they may not have had the caliber of training you'd want as an instructor - are you as instructor for those classes encouraged to just refuse to teach/dive with a student if you feel like they're not competent enough, including on the subject of being a confident independent diver?
