The link you post says the OP committed suicide in 2012. According to the OP's update page, the site has been updated throughout December of 2013:

Edit: for example, there was a page added recently on Node:
`2013/12/05: Added ‘harmful’ page about Node.js.`
(which unfortunately is down)
Edit 2: I think cat-v is now a series of sites, and each domain may be maintained by a separate person (the one under discussion is harmful.cat-v.org), so it may not all be the work and opinion of Uriel: http://webcache.googleusercontent.com/search?q=cache:JL12jkr...
