You shouldn't read too much into the amount of people pressing the button in terms of malice, but you can read into it in terms of negligence, lack of caution or impulsiveness. It's how many people saw a big red button and pressed it without first checking what it does. It's how many people took the chance that pressing it may do something bad even without the launch codes.
I was also curious what happens if you press the button and don't enter the code, but didn't check, because I view pressing the button as something you just don't do - I wouldn't do it even if a site admin specifically told me "you can press the button without any consequence".
Though, having pressed the button, it was a good idea to publish how it looks, and you satisfied my curiosity.
Just found this post through your response to Tom VanAntwerp on twitter. There's a sequence of questions and posts on LessWrong made by me and a few others that's about this topic. I suggest checking it out for ideas, discussion, and references to a few things that already exist (though they're mostly agreed to be insufficient).
Perhaps also consider cross-posting this to LessWrong.

80,000 hours made an article calculating the chance any existential risk will happen (combined their probabilities), not sure if this fully applies to what you meant, but it's something.
