So, it sounds like the individual is complaining that he didn't mention them, but also complaining about Sony sueing them, and somehow manages to blame him for Sonys actions? Like Sony gave them credit they didn't want, but they want to complain about not getting the credit they didn't want?
It's as if you gave an academic lecture on a casino's vulnerability to being robbed, and then someone actually went and robbed the casino. You can be mad at the asshole who robbed the casino for two reasons; A: he's put you in hot water that you would have avoided without the robbery; B: he took credit for discovering the vulnerability (or at least didn't correct people who assumed he must be a real hotshot at casino security design)
