The responses to his tweet calling him irresponsible are consistent with the tone of this remark. "This can help the bad guys". Nevermind the fact that there's no details in the tweet relating to the actual vulnerability or exploit.
To be clear: I don't know what relationship (if any) Graham Cluley has to the people being jerks to Tavis, and it's possible that this quote was taken out of context. However, given the backlash Tavis's tweet summoned from some Twitter users with inflexible opinions about disclosure ethics, and this alien remark in the article, I'd hedge on the two being related.
