I was about to comment this. He says he went public to raise awareness about allegedly being illegally detained in a "fake mental hospital". Obviously anything is possible, but that sounds a lot like he could've been legally detained and doesn't really understand the law i.e. he could've been a danger to himself or others.

His other bombastic comments to press and relatives also make him sound insecure and immature. Obviously he had to be somewhat adept and dedicated to gain access, but he didn't discover any incredible exploit here. He also takes credit for discovering a well known zero-day but admits he had nothing to do with the code for the exploit. To me that supports the idea that he hangs out in black hat circles because he wants to be one of the 'cool kids', put in the time and got lucky. I imagine the press love that because a lot of the public doesn't really know the difference.
