The comments, on the blog that you link to, mention Ted Kaczynski. This reminded me of my own comment

Think about the date: 1995. The Kaczynski Manifesto marks the end of an era. Nobody today would start a terrorist campaign aimed at getting his manifesto published in a newspaper. It is not just that newspapers are dying and that no-one believes what they read in newspapers anymore, especially not opinion pieces and manifestos.

Now-a-days you put your manifesto on a website and discuss it on Reddit. If it is well written and provocative it will be discussed and pulled to pieces. The delusion that did for Kacynski, and his victims, was that if only he could get the message out, it would change the word. Now-a-days you can get your message out, if not to a mass audience, at least to curious intellectuals. You get to the stage Kacynski never reached, of talking it over and finding that others are not persuaded and have their own stubbornly held views, very different from your own.

1995, the very end of the solipsistic era. In the new internet era there is no hiding from the fact that others read your manifesto, find some of it true, some of it false, some of it confused, and then ask you to read their, much better manifesto :-)

Perhaps my final point needs to be spelled out explicitly. You cannot expect other intellectuals to read and seriously engage with your door-step manifesto unless you are willing to hang around and read and seriously engage with their door-step manifesto. But you cannot do that if you are dead. So suicide is forbidden.

Alternatively: there is an implicit deal here - I'll read yours if you'll read mine. Killing yourself breaks the deal, and damns you to obscurity.
