grauniad
I got the impression from the blog post that a son may have clicked on links possibly relating to how bombs are made. Perhaps the FBI were monitoring who clicks on those links, and then checked for further search activity etc.
I'm not suggesting any of this is warranted obviously (Terrorism isn't a real threat at all), but it does look like it was more than 'just' search terms.
Breaking the law, is breaking the law. However noble your intent.
He broke the law. Then he committed suicide. I don't think there's much debate to be had about where any blame lies.
The Guardian is extremely sociliast in its reporting. That's just not popular. You're not going to make any profit with that political viewpoint. (Although you'll certainly be popular on Reddit, the BBC, and other left leaning communities).
To make money, you need to be center / center right to appeal to most people. That's why newspapers like "The Sun" and "Daily Mail" absolutely dwarf "The Gruaniad" in readership.
If anything, to me it smacks of hypocracy rather than irony. It would be like a campaign setup to promote vegetarianism, bankrolled by a side venture selling beef burgers.
