If anything, Im critizing his writing style, the blog article is not fun to read as it comes from a presumptions and arrogant/entitled position.
Or maybe its just me I dont see anything funny in that article, I just dont find the poking at virtual Linux users and people interested in cracking from a position of authority funny.
Effectively the entire article is making fun of hackers, people who are curious how to break software and make it do unspecified things, people who dare poke and dare crack. But its his software, so it is ok for him to make fun of others right?
The cracking culture is many peoples first step into hacking and programming, we wouldnt be here if all of us really payed for the stuff we used as kids.
