From the article:
>I didn’t know much about most of that a few weeks ago when intimate texts messages from me were published in the National Enquirer. I engaged investigators to learn how those texts were obtained, and to determine the motives for the many unusual actions taken by the Enquirer. As it turns out, there are now several independent investigations looking into this matter.
AMI showed up on Bezos's rader after they published his intimate text messages. Gawker showed up on Thiel's radar after they outed him. They both then went investigating to see if there was some illegal activity that these media companies were engaged in.
