I don't get your reasoning? You're agreeing with the author but are not?

The author argues that open CTFs are done for because of rampant cheating. You're agreeing with that, don't you?

The title is "AI has broken the open CTF format". If the format is "open CTF" then it is very specifically open.

As to your second question: Yeah, I believe having open CTFs was a good idea.

ah my bad. You're right, the author specifically states 'OPEN CTFs'. I think that keyword slipped my mind by the time I was at the end of the article.

So my question then becomes, what will realistically be lost if CTFs move to a form that requires teams and individuals to sign up?
