There’s already many people who have responded to that essay, taking up the #StunningAndBrave position that flooding the Internet with CP is actually bad.

By analogy, consider Eliezer Yudkowsky’s arguments against AI. For those who don’t know, Yudkowsky is a high IQ rationalist who thinks that AI is going to kill everyone, and so he thinks the only reasonable solution is to start bombing data centers.

Which is to say, if you actually think about the sequence of events that would make such a thing possible, it means we're probably already in an apocalypse.
