Amber Scorah gave one at a TedX event which is more local and centralized than an actual TED conference, and hers wasn't just about bagging on the religion, she's a big parental leave advocate and talks about dangerous daycares, etc:

There's also a big difference between her and that cockroach:
"She was named one of the 100 most influential people in Brooklyn culture by Brooklyn Magazine. Her writing has appeared in The New York Times, The Believer, The Boston Globe, The Cut, The Globe and Mail and USA Today."
Lloyd has to kiss Trey Bundy's ass and suck up to Rinder for screen time on their sites and shows, whereas Amber is a real, accomplished writer. Her book had a real publisher (Penguin) whereas he just slapped together and self published an 800 page brick.
I can't imagine Lloyd having success at a real conference with people who aren't all xJWs desperate for someone to speak up about the religion. Remember the video I posted about his cringe interview with BBC where he rambled on about nothing? Imagine 18 minutes of that.
