I struggle with this too. I have a student who is OBSESSED with hacking. He's hoping that after this class, he will be able to "hack" all sorts of systems. He is a good kid overall, but I also don't think he gets that what he is doing is a crime.
I have talked about the difference between "white hat" and "black hat" hackers but he is still really curious about it. I am hoping to get him plugged into some competitions at our local college so he can see how those skills can be used for good.
Personally, I think you could anchor this in a discussion of ethics when it comes to CS. CSP is supposed to show how CS is every where, and you just identified a key "white space" for kids. Connected to the ethical (and legal) ramifications of censorship, I think you have a good argument for doing this with students. I don't think we can say "ignorance is bliss" here... I personally like the idea! I could even see tying this to a guest speaker about censorship etc...
I'd love to hear how it goes!
