There is a (conspiracy) theory that the writer was actually working for a government since a lot of the instructions don’t work, or would potentially kill the person making it. Thus anyone who tried to follow it would not get results or die from making a project at home.

That said, zero proof. Hence the conspiracy in conspiracy theory.
