I did not see that bit. I came upon this many years ago. TED has changed its thought process and stances on multiple subjects since then. Adding such disclaimers is a new turn of editorialism.

If you want to go down the rabbit hole of research that both recognizes and refutes the assertions, you will find more opinions expressed than facts. But neither the facts nor opinions are interesting. It is the narratives and the lessons derived that hold more value. And that video expresses some of them.

There is a longer documentary style video on the same subject by the same speaker.

And my search turned up this bit: https://pornstudycritiques.com/gary-wilson-wins-second-legal...

There is a movement out there trying to crush this video.
