He's referring to the linked article, so your personal attack is misdirected.

'With a few clicks and an affirmation that the subject is believed to be engaged in terrorism, espionage or nuclear proliferation, an analyst obtains full access to Facebook’s “extensive search and surveillance capabilities against the variety of online social networking services.”'

But that's not a personal attack. The comment also mentions speculations about "rejoice" when they opened the Facebook graph, after believing what the article says about FB's methods of data sharing without further questioning.

Again: Questioning the motives behind an attempt of persuasion argument isn't a personal attack.
