Which part and in what way? Clearly the blog post is not satire, since the method works, and the license cannot be satire as it seems like it would be legally sufficient to prevent people from using it, which is exactly the stated purpose of the license. It's also implied that the author has received requests to change the license so others can use the package, which have been denied. The author even went so far as to remind people in this comment thread that they don't want it to be used! The license is serious on its face and in practice. Where is the joke?
