New Scientist has a thriving and coherent Tech element. Sabu's motivations may be heavily political but the purpose of the interview is to provide a direct insight into one of the key members of LulSec and help people understand that their motivations aren't exclusively 'for the lulz'.
Regardless of Sabu's motivation, I am confident that a huge percentage of New Scientist readers will find the article fascinating and thought provoking as I certainly did.
I gave a lot more credence to the article having read it on New Scientist as opposed to what my opinion may be if the same interview was published on Cracked or Fox News.
