Yes, it was a vendor interview piece with a linkbait-and-switch title. (Cloudfare didn't keep Lulzsec "safe", they kept their website up.)

But NewScientist's primary audience is not web hosting specialists. So for their audience I expect it was mildly educational.

If I remember correctly some guy posted lulzsec member identities online after simply following them in irc..

Indeed, but none of them led to the arrests.

It's very likely that they were false IDs created for diversion.
